Calculate the reduction in volume after 99.00 g of sulfu-
ric acid is added to 1.000 g of water. The density of water
is 1.000 g/mL, that of sulfuric acid is 1.8305 g/mL, and
that of 99.00% sulfuric acid in water is 1.8342 g/mL.
2.179
Calculate the density of a solution prepared with
54.08 mL of sulfuric acid and 1.00 mL of water. The
density of water is 1.00 g/mL and that of sulfuric acid is
1.8305 g/mL. The volume of the solution is 54.52 mL.
2.180 Calculate the reduction in volume after 30.00 g of sul-
furic acid is added to 70.00 g of water. Assume that the
density of water is 1.000 g/mL, that of sulfuric acid is
1.8305 g/mL, and that of 30.00% by mass sulfuric acid
in water is 1.2185 g/mL.
2.181 Calculate the density of a solution prepared with
16.39 mL of sulfuric acid and 70.00 mL of water. As-
sume that the density of water is 1.000 g/mL and that of
sulfuric acid is 1.8305 g/mL. The volume of the solu-
tion is 82.068 mL.
2.182 In light of the answers to the Problems 2.178-2.181,
state why the method of determining volume of irregu-
larly shaped objects in Figure 2.2 would not work for
sugar crystals.
