Answer:
2
Explanation:
The molecular formula can be derived from the empirical formula of a compound and the molecular mass as follows:
(C2H4O)n = 88g/mol
Where;
C = 12, H = 1, O = 16
{12(2) + 1(4) + 16}n = 88g/mol
{24 + 4 + 16}n = 88
(44)n = 88
44n = 88
Divide both sides by 44
n = 88/44
n = 2
The molecular formula is: (C2H4O)n
= (C2H4O)2
= C4H8O2
According to the question asked, oxygen has a subscript of 2 in the molecular formula.
