When 2.95 of hydrogen peroxide solution decomposes, 36.9 ml of oxygen gas is evolved. The oxygen gas is collected over water at a temperature of 24C and at a total pressure of 762mmHg. The density of the hydrogen peroxide solution is 1.01 g/mL and the solution contains 3.40% H202 by mass. The vapor pressure of water at 24C is 22 mmHg. Based on this data and information calculate the molar volume at STP.
