a. What is the volume occupied by 0.265 mol of helium gas
at 1.28 atm and 307 K?\
b.A cylinder contains 27.5 L of oxygen gas at a
pressure of 1.6 atm and a temperature of 307 K. How
many moles of gas are in the cylinder?\
c.An experiment shows that a 234 mL gas sample has a
mass of 0.443 g at a pressure of 745 mm Hg and a
temperature of 34 ∘C. What is the molar mass of the
gas?
