Classify the following type of stoichiometry problem:
How many grams of zinc must react with an excess volume of hydrochloric acid to yield 0.500 g of zinc chloride?
mass-mass problem
mass-volume problem
volume-volume problem
mole-mole problem
none of the above
To classify the type of stoichiometry problem, we need to analyze the given information. In this case, the problem asks how many grams of zinc are needed to react with a certain amount of hydrochloric acid to produce a specific amount of zinc chloride. This problem involves the conversion of mass (grams) to mass (grams).
Therefore, the correct classification for this stoichiometry problem is a "mass-mass problem."
