Molar Mass Calculator

Look up or enter molar mass for common compounds and elements.

Molarity Calculator

Calculate molar concentration (mol/L) from mass, molar mass and volume.

Dilution Calculator

Find the final concentration or volume after diluting a stock solution (C₁V₁ = C₂V₂).

Stoichiometry uses mole ratios from a balanced equation to calculate how much product can be formed from a given amount of reactant.

Percent yield compares actual to theoretical yield, reflecting real-world losses from side reactions, transfer losses and equilibrium.

\% \text{ yield} = \frac{\text{actual yield}}{\text{theoretical yield}} \times 100
