Frequent question: How many moles are present in 205 g of helium?

The answer is 4.002602. We assume you are converting between grams Helium and mole.

How many moles of helium are in a gram?

If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams. We can use the molar mass as a conversion factor. Two moles of helium times four grams of helium per mole of helium is equal to eight grams of helium.

How many moles are present in 54 grams of helium?

One mole is equal to the total mass of the molecule. We know one mole is equal to 4 gm of Glucose molecule. Now a number of moles in 54 gm of Helium is (n) = 54/4 n = 13.5 moles. The number of moles in 54 gm is 13.5 moles.
