Student collects 47.56mL of hydrogen gas over water at a temp of 22C. The atmospheric pressure is reported to be 29.78 in Hg. I have found that atmospheric pressure in mmHg is 756.412, and the vapor pressure of water at 22C is 19.827 mmHg. a. what is the pressure of dry H2 in mmHg? and in atm? Assuming the ideal gas behavior, how many moles of H2 gas were collected?
