We know from reading the label on the bottle (“18.0 Molar”) that one liter of reagent
contains 18.0 moles of H2
SO4
. This means that 1 ml of reagent contains 0.018 moles of
H2
SO4
. Therefore,
1 ml x ml
_________ = ______.
0.018 moles 1 mole
Solving for x, we find that we need 55.6 ml of H2
SO4
reagent.
