Answer» Answer: 1 mole of hydrogen atoms got 1 gram, so 2 moles of them got 2 grams. 1 mole of oxygen atoms got 16 grams. Therefore, 1 mole of H2O got 18 grams. 2 moles of H2O gets you 36 grams. Chlorine GAS Cl 2, has a relative molecular mass of 71 because it is made up of TWO Cl atoms, each of Mr 35.5. 63.9976 g per mole of oxygen. From here, the answer is SIMPLE. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g Explanation: |
