1. At 159 mm Hg, the solubility of gaseous oxygen ($O_2$) in blood is 0.44 grams per
100 mL of blood. If pure oxygen ($O_2$) is administered to the patient at 760 mm Hg,
what is the solubility of oxygen in the blood (in units of grams per 100 mL),
assuming that Henry's Law is obeyed?
2. How many moles of $HNO_3$ are in 675 mL of 0.60 M $HNO_3$?
