# Chemistry Calculator

> Fifteen chemistry formulas with step-by-step working: moles and molar mass, molarity and dilution, pH and pOH, gas laws, stoichiometry, ppm and photon energy.

Free chemistry calculator for 15 formulas: moles from mass, molarity, molality, M1V1=M2V2 dilution, pH and pOH, weak acid pH, ideal gas law, gas density, Boyle’s and Charles’s laws, ppm, percent yield, stoichiometry and photon energy - all with steps.

## How It Calculates

- **Formula:** formula-specific: e.g. n = mass ÷ M, pH = −log₁₀[H⁺], PV = nRT

- **Built-in formulas:** 15 (moles, molarity, dilution, ph-from-h, poh-from-oh, ph-weak-acid, ideal-gas-volume, gas-density, boyles-law, charles-law, molality, ppm-mass, percent-yield, stoich-mass, photon-energy)

All calculation runs locally in your browser; results update as you type and include the substituted working.

## From Moles to Gas Laws in One Place

AiLoveKit's **chemistry calculator** covers the calculations students meet across general chemistry: converting mass to moles and molecules, preparing and diluting solutions, reading pH, predicting gas behavior and working stoichiometric yields.

## Lab-Ready Details

- **Every step shown** - dilution factors, intermediate mole amounts and pOH values appear with the main answer.

- **Sensible defaults** - water’s molar mass, acetic acid’s Ka and dry-air density preload so results appear immediately.

- **Instant** - change any input and the solution rewrites itself, perfect for homework and lab prep.

## Frequently Asked Questions

**Which topics are covered?**

Molar quantities (moles, molecules), solutions (molarity, molality, dilution, ppm), acids and bases (pH, pOH, weak acids), gas laws (ideal gas, Boyle, Charles, density), stoichiometry and yield, and photon energy.

**How do I find molar mass?**

Sum the atomic masses from the periodic table - e.g. water H₂O = 2 × 1.008 + 15.999 = 18.015 g/mol, which is the built-in default.

**What temperature units do gas laws use?**

Kelvin. Convert with K = °C + 273.15. Pressure defaults use pascals (1 atm = 101,325 Pa).

**Is the weak acid pH exact?**

It uses the standard approximation [H⁺] ≈ √(Ka·C), accurate whenever dissociation is small relative to the concentration - the case for most coursework.
