Periodic table
Tap any element for its properties. Coloured by category.
Equation balancer
Enter an unbalanced equation — get the balanced coefficients. e.g. H2 + O2 = H2O
Try: Fe + O2 = Fe2O3 · C3H8 + O2 = CO2 + H2O · Al + HCl = AlCl3 + H2
Ideal gas law PV = nRT
Leave ONE field blank (or 0) — it will be solved. R = 8.314 J/(mol·K).
Molar mass
Enter a formula to get its molar mass. e.g. C6H12O6, H2SO4, Ca(OH)2
