By definition, carbon-12 has a molar mass of 12 g/mol. Thus, to calculatethe stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction.

Answer:
stoichiometry means that the number of moles on both the reactant and product side is the same
Explanation:
rule:
aA + bB ---> cC + dD
a,b,c, and d are coefficients for the molecules A, B, C, and D
so number of moles of A is given and that of B too.
RA(ratio of A) = number of moles of A / coefficient of A(a)
RB(ratio of B) = number of moles of B / coefficient of B(b)
ratios of A and B must be equal so that the reaction is stoichiometric
and this is how you do calculations
note: all other calculations are done according to stoichiometric ratios
