Which option shows how you would set up to solve for the following problem: How many molecules are there in 31.8 moles of water? (Molar Mass of H2O =18)

• 31.8/18

• 31.8 X 18

• 31.8 X (6.02 X 10^23)

• (6.02 X 10^23)/31.8

When converting from moles to atoms/molecules, moles is multiplied by:

• Avogadro's Number

• Moles

• Molar Mass

• 6.02X10^23
