Web5 sep. 2024 · Explanation: Assuming that helium behaves as an ideal gas, we know that a mole of ideal gas occupies 22.4 litres at STP. The atomic weight of helium is 4 g/mol, so 6 g is 1.5 moles. The volume occupied at STP, therefore, is 22.4 x 1.5 = 33.6 litres. WebIs 1g 1 mole? Yes, of course! As we know that there are equal gram atoms present in one mole of atom. So we can say 1 gram of an atomic particle is equal to the moles present … WebOne mole of any element is equal to the relative atomic mass of that element in grams. 1 mole = 24 g of magnesium. Step 2: Calculate the amount of moles in 6 g. 6 24 = 0.25 moles. Step 3: Convert the moles to number of molecules. 1 mole = 6.02 × 10 23 molecules. 0.25 moles = 0.25 × 6.02 × 10 23 = 1.51 × 10 23 molecules. litany souls purgatory
