Chemistry
Half-Life and Radioactive Decay Calculator
Determine how much of a radioactive substance remains after any period of time, or back-calculate the half-life from measured decay data. Ideal for radiometric dating, nuclear physics coursework, and radiation safety assessments.
Fill in the required fields to see your result.
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.
