The molecular formula mass of this compound is 120 amu . What are the subscripts in the actual molecular formula

Explanation:

From the given information:

Assume the molecular formula to be:

Then, the molecular mass will be = 12a + 2a + 16a = 30a  (since the C = 12, H = 2 & O = 16) respectively.

Thus;

30a = 120

a = 120/30

a = 4

Thus, the molecular formula:

the objects have the same charge is correct.
