Answer:
0.086
Explanation:
A 5.2 molal aqueous solution of methyl alcohol indicates that 5.2 moles of methyl alcohol are present in 1 kilogram (or 1000 g) of water. Water has a molecular weight of 18 g/mol.
(100g)/18g/mol=55.56 mol
5.2 mol/(5.2mol+55.56 mol)=0.086
the answer is 8 electrons
Subtract the mass of the CuSO4⋅ 5H2O from the mass of CuSO4 is the right one
The correct answers are C and D.
