Answer:
HgSO4
Explanation:
Data obtained from the question include:
Hg = 33.8g
S = 5.4g
O = 10.8g
Divide by their molar mass
Hg = 33.8/201 = 0.168
S = 5.4/32 = 0.169
O = 10.8/16 = 0.675
Divide by the smallest
Hg = 0.168/0.168 = 1
S = 0.169/0.168 = 1
O = 0.675/0.168 = 4
The empirical formula is HgSO4
