Chemistry
Chemical Reaction Yield Calculator
Compute the theoretical yield (in grams) of a chemical reaction from the limiting reactant’s mass, the reactant and product molar masses, and the stoichiometric ratio. The first step in evaluating reaction efficiency — compare against your actual experimental yield to get percent yield.

Chemistry
Molecular Weight Calculator
Compute the molecular weight (molar mass, g/mol) of a CHON-containing molecule from the number of carbon, hydrogen, oxygen, and nitrogen atoms in its formula, with an optional isotope-correction factor. Useful for routine stoichiometry on organic and biological molecules where C, H, O, and N dominate the elemental composition.
