B) Accurate is the right answer
Answer:
360.4 grams
Explanation:
The first step is to find the molecular mass of H2O. The molecular mass of a molecule is the atomic masses added altogether. Because there are 2 hydrogens, we need 2x the atomic mass. 2(1.01) + 1(16.00) = 18.02 amu.
The molar mass of H2O is 18.02 g/mol. This is the unit converter to change from moles to grams

It oxidized cu since it gains electons.
