A type of stoichiometric calculation that doesn't involve the use of gram formula mass is volume-volume problem.
A stoichiometric calculation can be defined as a type of calculation which is typically used to measure the quantitative relationships that exists between two or or more chemical compounds that are undergoing a chemical reaction.
This ultimately implies that, a stoichiometric calculation is generally used to study the quantities of reactants and products of two or or more chemical compounds before, during, and after a chemical reaction.
In this scenario, volume-volume problem is a type of stoichiometric calculation that doesn't involve the use of gram formula mass.
