## What is the mole of helium?

The molar mass is the mass of one mole of an element and is found on the periodic table. 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.

## How do you calculate one mole of helium?

The atomic weight for helium on the periodic table is 4.002602. All elements have its atomic weight mentioned in the periodic table. So it can be found out easily from the periodic table itself. Therefore, one mole of helium has a mass of **4.002602 g**.

## What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is **15.998 grams** and the mass of one mole of hydrogen is 1.008 g.

## How many moles are in AR?

To solve this let us find out the molar mass of Argon, it is 39.948 g/mol or roughly 40 g /mol. It means that one mole of Argon weighs 40g. 607g / 40g moles or **15.175 moles**.

## What is mole of water?

A mole is a unit measuring the quantity of anything. Water (H_{2}O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be **2 moles of hydrogen atoms plus 1 mole of oxygen atoms**. weight of water = 2(1.0079) g + 15.9994 g. weight of water = 2.0158 g + 15.9994 g.
