Molar mass
Molar mass. The mass of one mole in grams: add the atomic mass of every atom in the formula. Masses. Standard atomic masses to two decimals, hydrogen 1.008, every element to uranium. Typing. Ca(OH)2, (NH4)2SO4, CuSO4.5H2O and K4[Fe(CN)6] all work.

1 mol of Al = 6.022 × 10²³ atoms
At 1 atm (older value): 22.40 L
Add up the atoms
- Aluminium: 1 × 26.98 = 26.98 g

Molar mass of aluminium: quick answers
What is the molar mass of aluminium?
The molar mass of aluminium, Al, is 26.98 g/mol. So 1 mol of aluminium has a mass of 26.98 g.
How do you calculate the molar mass of Al?
Add the atomic masses of all the atoms: 26.98 = 26.98 g/mol.
How many moles are in 100 g of aluminium?
Divide the mass by the molar mass: 100 ÷ 26.98 = 3.71 mol of Al.
