Question

What is the number of moles of 27.6 grams of lithium

Answer 1

one mole

Step-by-step explanation:

one mole

Lithium for instance has an atomic mass of 6.941 grams and this is equal to one mole of lithium. This is why we state the atomic and molecular masses in units of grams per mole or g/mol.

Answer 2

Lithium's atomic weight is 6.94 g/mol.


`27.6 g Li ((mol)/(6.94 g)) = 3.98 mol Li`
