Calculate reactant and product amounts

Reactant Mass

Unit

Reactant MW (g/mol)

Product MW (g/mol)

Mole Ratio (product:reactant)

Reaction Yield (%)

Theoretical Yield

Mass Input

100.00 g

moles = mass ÷ molecular weight

product moles = reactant moles × (product coeff ÷ reactant coeff)

theoretical mass = product moles × product MW
