We can now set up this problem using dimensional
analysis just like a “regular” stoichiometric problem:
100 ml 1 L .2 moles HCl 1 mole Ca 40.08 g Ca
103 mL 1 L 2 moles HCl 1 mole Ca
Notice that we use the MOLAR CONNECTION or
MOLAR RATIO from the balanced equation just like
we would normally do in a stoichiometry problem.
Notice, also, that all of the units cancel properly giving us
grams in our answer which is:
.4 g of calcium (1 sig fig)
