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.

How many moles of helium are present in 52g of helium?

There are 13 moles in 52g of helium.

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
