Why do we need to convert mass to moles in stoichiometry problems?

Answer:
That is an extremely common question when first using stoichiometry. The answer is that you are converting based on number, not on mass. ... This number is then used in a ratio conversion based on the mole ratios in the balanced chemical equation. We then use the molar mass to convert out final answer into grams.

Answer:
Big, because atoms and molecules are way too small to count, so we mass large numbers of them instead, and use molar mass to convert to the NUMBER of moles of them.
This number is then used in a ratio conversion based on the mole ratios in the balanced chemical equation.
