How many moles of Helium weigh equal to the mass of 1 mole of Oxygen molecule?
Gram molecular mass of O2 = 32g = 1 mole
Gram atomic mass of Helium = 4g = 1 mole
So 8 moles of Helium gas weighs equal to 1 mole of Oxygen molecule
Weight of how many moles of helium is equal to the weight of 1 mole of oxygen molecule?
How many moles of helium will have a mass equal to the mass of 1 mole of oxygen gas?
2 moles of oxygen gas contain how many numbers of oxygen molecules?
