Answer is although the question should have 3 significant figures.
<h3>What is
significant figures?</h3>
Fe + CuSO4 --> Cu + FeSO4
It is already balanced
1 mol Fe : 1 mol CuSO4 : 1 mol Cu : 1 mol FeSO4
- atomic masses of Fe and Cu
Fe: 55.8 g/mol
Cu: 63.5 g/mol
number of moles = mass in grams / atomic mass = 93.7 g / 55.8 g/mol = 1.679 mol
1 mol Fe / 1 mol Cu => 1.679 mol Fe / 1.679 mole Cu
- mass of Cu in 1.679 moles Cu
mass = atomic mass * number of atoms = 63.5 g/mol * 1.679 moles = 106.6 g = 107 rounded to 3 significant figures.

CH3OH IS MOLECULES OF ALCOHOL
Water is not part of that compound. What is the chemical equation?
Answer:
9.90
Explanation:
ph= -log (H+) = -log( 1.25×10^-10)
which equals to 9.903
so the answer is 9.90
