Title: If a 92.1 ml sample of gas has a partial pressure of 755.03 mmHg at 23.00 Celsius, how many moles of ... Post by: brzezsabbb on Apr 5, 2017 If a 92.1 ml sample of gas has a partial pressure of 755.03 mmHg at 23.00 Celsius, how many moles of gas are present
If a sample of gas contains 0.00388 mol of gas and has a mass of 0.23, what is the molar mass of the gas(g/mol)? A sample of gas is collected over water at 21.0 Celsius and 0.97 atm. If the vapor pressure of water at this temperature is 18.65 torr what is the pressure of the gas (in mmHg)? ...I need help, thanks!

If the vapor pressure of water at this temperature is 18.65 torr what is the pressure of the gas (in mmHg)? pressure = 0.97 x 760 = 737.2 torr water pressure = 18.65 torr pressure of gas = 737.2 - 18.65 = 718.5 torr pressure of gas = 718.5 mmHg |
