Kassandra Reilly · Answer 1

There are 2.16 moles of Lithium in 15 grams.

Look at the periodic table to find the molar mass of an element. Molar mass of Lithium is 6.9410 g/mol.

Use dimensional analysis:

15g * (1mol / (6.9410g/mol)) = answer

The grams cancel out leaving you with your number in mol units.

Multiply it out and you get 2.16 moles of Lithium.
