**How to calculate moles.?**

To calculate the moles of solute you will need to divide the weight in grams you have added to the solution by the weight in grams of one mole. For this example, use sodium chloride: NaCl. The weight of one mole, rounded to the nearest tenth, is the atomic weight of sodium, 23g, plus the atomic weight of chorine, 35.5.

#### How many atoms are in hydrogen?

There are two atoms in hydrogen. The molecular formula of hydrogen is H2, which means one molecule of hydrogen has two atoms.

#### How do you calculate moles of water?

There are 55.346 moles in 1 liter of pure water. This is calculated by dividing the density of water, which is 997.07 grams per liter, by the molecular mass of water, which is 18.02 grams per mole. Molarity is found by dividing the number of moles of a substance present by the size of the sample.

**What is the molar mass of hydrogen?**

Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = 10.08 g.
