1. Iodine, I2, is a solid at room temperature but sublimes

(converts from a solid into a gas) when warmed. What is the temperature in a

73.3-mL bulb that contains 0.292 g of I2 vapor at a pressure of 0.462 atm?

2. A cylinder of medical oxygen has a volume of 35.4 L, and

contains O2 at a pressure of 151 atm and a temperature of 25 °C. What volume of

O2 does this correspond to at normal body conditions, that is, 1 atm and 37 °C?
