You need to properly write your question. I hope you placed mistakenly 8 instead of multiplicity sign (*). Also I would like to make sure that you indeed mean ONE water molecule in one unit of CuSO4*H2O. Typically well know hydrate of CuSO4 has a formula CuSO4*5H2O. Another hydrate such as CuSO4*H2O does also exist but You will need to confirm it before I will give you my answer.
The mass percent of hydrogen (H) in H2O (water) is 11.11%. This can be calculated by dividing the mass of hydrogen by the total mass of the compound (2g H / 18g H2O * 100%).
"Water" = the common name for 100% h20.
18.02 AMU.
If you think to molar mass, the value is 18 g.
water (h20)
The answer is H20
1 L of H20 has a mass of 1 kg
51.2 g H20
Yes, mass percent and percent by mass are the same concept. Both terms refer to the percentage of a component in a mixture by mass.
lets see. H20 you have 2.016 grams of hydrogen here to 16.0 grams oxygen 2.016/16.0 X 100 = 12.6% hydrogen by mass H2O2 you have the same 2.016 grams hydrogen here, but you have 32.0 grams oxygen in this molecule 2.016/32.0 X 100 = 6.3% so H2O has the higher percent by mass of hydrogen

Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
