Derive the chemical formula of a substance if it is known that the mass fraction of sulfur in this substance is 0.5 (50%), the mass fraction of oxygen is 0.5 (50%). The relative molecular mass is 64.
Given:
W (S) = 0.5
W (O) = 0.5
Mr (SxO4) = 64
SxOy-?
Decision:
W = Ar * n \ Mr
x = 0.5 * 64 \ 32 = 1
y = 0.5 * 64 \ 16 = 2
Answer: SO2
