Question

How many moles of LiOH are in 67.03g?

Answer 1

Collect the molar masses of each element contained in LiOH.

• Lithium (Li) has a molar mass of 6.941 g/mol
• Oxygen (O) has a mass of 15.999 g/mol
• Hydrogen (H) has a mass of 1.008 g/mol

Together, LiOH has a molar mass of 23.948 g/mol.

Convert the given amount of LiOH from g to mol:

(67.03 g) * (1/23.948 mol/g) = 2.799 mol
