Question

The relative formula mass of a compound with formula XS0, is 120. Calculate the ralative

atomic mass of Y.
[Relative atomic mass: S, 32; 0, 16]

Answer 1

72

Step-by-step explanation:

Relative atomic mass of YSO = Relative atomic masses of Y + S + O

This implies; Y + 32 + 16 = 120

Y = 120 - 48

Y = 72

Hence, the relative atomic mass of Y = 72
