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

Contents

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.
