72 is the answer to this problem

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

there are no choices to this, can you give us some choices so that i can answer it

step-by-step explanation:

it should be described as a proper fraction.
