Reference no: EM13211608

When gases are collected using displacement of water,some water vapor mixes in with the gas being collected.35.2 ml of H2 gas was collected over water at a temperature of 21 Celsius degree. If the barometric pressure was 758 mmHg,how many grams of water vaor mixed in with the hydrogen gas?
