1) The barometric pressure is reported to be 605.5 torr and the temperature of the water is 22.5 c what is the pressure of dry hydrogen gas in the eduiometer?
2) How is the mass of the gas filling the Erlenmeyer determined?
3) What has to be done to the position of the eudiometer to ensure that the total presure of gas in it is the same as the barometeric pressure?
