Answer 1

1. One mole H,O contains 6.023x103 H,O molecules. Calculatethe number of H2O molecules in 4.56 moles of H2O using the following conversion: 4.56 moles of H2Ox 6.023x1025 H molecules moles of H,O 2.75x103 H,O molecules 2. One mole H,O contains 6.023x103 H,O molecules. Calculate the number of moles of H,O in 1.62x10 H,O molecules using the following conversion: 62x10 H,0 molecules 6023x10 H,O molecules moles of H,O 6.023 x 1023 H,O molecules -0.0269 moles of H,O
