Use Avogadro's Number to convert between moles and molecules
Avogadro's Number = 6.022 × 1023
So, this means that 1 mole of molecules = 6.022 × 1023 molecules
Given 2.99 moles of water, we can use the relationship in bold to convert to molecules:
2.99 moles × 6.022 × 1023 molecules/1 mole = 1.80 × 1024 molecules
