The mass fraction of mercury and oxygen in bivalent mercury oxide is as follows, first we write the formula for bivalent mercury oxide, which looks like this:
Further, to calculate the mass fraction of oxygen in bivalent mercury oxide, we use the following formula:
W = (n × Ar × 100%) / Mr
Where W is the mass fraction of the substance,
n is the number of atoms in a molecule,
Ar is the relative atomic mass of the element,
Mr is the relative molecular weight of the entire substance.
Further oxygen Ar
Ar (O) = 16
then we calculate the relative molecular weight of the whole substance:
Mr (HgO) = 201 + 16 = 217
Next, Substitute all known values into the formula and get the following solution:
W (O) = 16 × 100% / 217 = 7.37%
Next, we calculate the mass fraction of mercury
W (Hg) = 100% – 7.37% = 92.63%
