Atomic mass of Helium is 40026 u. A gas mixture with a total pressure of 765 mmHg contains each of the following gases at the indicated partial pressuresCO_2 265 mmHg. Helium molecular weight.
Calculate i the mass of the helium. Molecular mass of helium Mass of one mole of helium molecules. And O_2 163 mmHg.
224 dm³ 224 liter. What is the mass of helium gas in the container. An unknown amount of Helium He gas occupies 102 L at 17 atm pressure and 342 K.
Mass numbers of typical isotopes of Helium are 3. Since the molar mass of 1 mol of helium is 4002602 this simply means the molar volume which is 224 dm³ 4002602. Atm the amounts of each gas present atequilibrium were 62 x 10-3 mol of CO 62 x 10-3 mol of H20 0994 mol of CO2and 0994 mol of H2.
One of the things this means is that a mole of Helium has a mass of 4003 grams. The question then is how many grams of helium fit in one mole. By flowing the gas through such a device at a constant rate measuring the flow rate in gramssec and multiplying it by the time.
