A 92.0-g sample of a liquid is placed in a 25.0-L flask. At 140 °C, the liquid evaporates completely to give a pressure of 0.900 atm.
a. What is the molar mass of the gas?
b. If the flask can withstand pressures up to 1.30 atm, calculate the maximum temperature to which the gas can be heated without breaking.
