Enter the full problem (numbers, units, and what you need to solve). Add your attempt if you want the solver to check your work.

2

Choose topic and output format

Select a topic (or Auto-detect) and pick Step-by-Step, Exam Style, Simple Explanation, or Final Answer Only.

3

Get a clean solution

Receive the solution with correct equations, unit handling, and a clear final answer you can copy into notes or assignments.

Before

How many grams of NaCl are needed to prepare 250.0 mL of a 0.150 M NaCl solution? (Molar mass NaCl = 58.44 g/mol)

After

Given: M = 0.150 mol/L, V = 250.0 mL = 0.2500 L Moles NaCl = M × V = (0.150 mol/L)(0.2500 L) = 0.03750 mol Mass NaCl = moles × molar mass = (0.03750 mol)(58.44 g/mol) = 2.1915 g Final answer: 2.19 g NaCl (3 sig figs)

Pro Tips for Better Results

Get the most out of the AI Chemistry Problem Solver with these expert tips.

Include units and what you’re solving for

Chemistry is unit-driven. Always paste values with units (g, mol, L, atm) and explicitly state the target (e.g., “find pH” or “mass of product”).

Paste the exact balanced equation if provided

If your worksheet gives a reaction, include it. If not, the solver can balance it—but including the equation reduces ambiguity.

Specify rounding rules

If your class requires 3 significant figures or specific decimal places, add that note so the final answer matches grading expectations.

Use Exam Style for studying

Exam Style outputs the essential steps and equations—ideal for building a repeatable process without extra narrative.

Who Is This For?

Trusted by millions of students, writers, and professionals worldwide.

Solve stoichiometry and limiting reagent problems with mole conversions and balanced equations
Calculate molarity, molality, dilutions, and solution preparation steps for lab work
Find pH, pOH, Ka/Kb, buffer pH (Henderson–Hasselbalch), and titration endpoints
Set up equilibrium expressions (Kc/Kp), ICE tables, and solve for concentrations or partial pressures
Work through thermochemistry (q = mcΔT), Hess’s law, and enthalpy changes with clean sign conventions
Balance redox reactions and compute cell potentials, ΔG°, and electrolysis quantities
Check homework solutions and identify common chemistry mistakes (units, coefficients, assumptions)

Chemistry Problem Solver that actually shows the working (not just the answer)

Chemistry homework can be weirdly punishing. You might understand the concept, but one missed unit conversion or a slightly off balanced equation and the whole thing collapses.

This AI Chemistry Problem Solver is built for those moments. You paste the question, pick the output style you want, and it returns a solution that is readable, organized, and based on the same steps your teacher or textbook expects.

Not magic. Just a clean process. With the math shown when you want it.

What you can solve with this tool

If it shows up in general chemistry, AP Chem, IB Chem, or intro college chem, it usually fits here.

Common problem types include:

  • Stoichiometry: mole to mole, gram to gram, limiting reagent, percent yield
  • Molarity and dilution: M1V1 = M2V2, solution prep, concentration changes
  • Gas laws: PV = nRT, combined gas law, partial pressure setups
  • Acids and bases: pH, pOH, Ka/Kb, buffers, titration logic
  • Equilibrium: Kc, Kp, ICE tables, Q vs K comparisons
  • Thermochemistry: q = mcΔT, Hess’s law, sign conventions, enthalpy
  • Redox and electrochemistry: balancing redox, E°cell, ΔG°, electrolysis
  • Kinetics: rate laws, integrated rate equations, half life

If you have a multi part prompt, like parts (a), (b), (c), just paste the whole thing at once. It tends to work better that way.

Choose the output format that matches what you need

This is the part people usually skip, but it matters.

  • Step-by-Step: best for homework, learning, and catching mistakes
  • Exam Style: shorter, still shows key equations and substitutions
  • Final Answer Only: quick check, but no working
  • Explain Simply: for when the concept itself is the blocker
  • Check My Work: paste your attempt and get corrections (premium)

A simple trick: use Step-by-Step while learning, then switch to Exam Style and see if you can reproduce it yourself without reading every line.

How to get more accurate chemistry answers

Chemistry is all about details. If you give clean inputs, you get clean outputs.

Try to include:

  1. All given values with units
    Like 0.250 L, not just 250.

  2. What the question is asking for
    “Find the mass of CaO formed” is clearer than “solve this”.

  3. Any provided constants or molar masses
    If your worksheet gives them, paste them. Even if you think you know them.

  4. Rounding rules or sig figs
    If your class wants 3 sig figs, say that. Otherwise you may get a “right idea, wrong format” situation.

A quick example (what the tool is doing behind the scenes)

Let’s say the prompt is:

How many grams of NaCl are needed to prepare 250.0 mL of a 0.150 M NaCl solution?

The logic is basically:

  • Convert volume to liters
  • Use molarity to find moles
  • Convert moles to grams using molar mass
  • Round correctly

And that’s the same structure you will see in Step-by-Step mode. Equations first, then substitution, then units, then the final answer.

Common chemistry mistakes this solver helps you catch

Even strong students miss these, constantly.

  • Forgetting to balance the equation before doing mole ratios
  • Mixing up mL vs L or g vs kg
  • Using the wrong molar mass (especially hydrates and polyatomic compounds)
  • Dropping units mid way, then guessing at the end
  • Confusing Kc vs Kp setups, or writing equilibrium expressions incorrectly
  • Sign errors in thermochemistry, especially with ΔH and q

If you are studying, one good routine is to solve it yourself first, then paste your work into “Check My Work” to see exactly where the first wrong step happened.
