There are two binary compounds of mercury and oxygen. heating either of them results in the decomposition of the compound, with oxygen gas escaping into the atmosphere while leaving a residue of pure mercury. heating 0.6498 g of one of the compounds leaves a residue of 0.6018 g. heating 0.4172 g of the other compound results in a mass loss of 0.016 g. determine the empirical formula of each compound.

and .

Assuming complete decomposition of both samples,

First compound:

; of the first compound would contain

Oxygen and mercury atoms seemingly exist in the first compound at a ratio; thus the empirical formula for this compound would be where the subscript "1" is omitted.

Similarly, for the second compound

; of the first compound would contain

and therefore the empirical formula

.
