1.Determine the mass ratios:
For compound 
: Mass of 
combined with 
of 
For compound 
: Mass of 
combined with 
of 
For compound Z: Mass of O combined with 
of 
2. Convert mass ratios to molar ratios using atomic masses:
Atomic mass of 
Atomic mass of 
3. Calculate the moles of oxygen per mole of bromine for each compound:
For compound X:
Moles of 
Moles of 
Mole ratio 
Therefore, the empirical formula for 
is 
.
For compound 
:
Moles of 
Mole ratio 
Therefore, the empirical formula for 
is 
,
For compound Z:
Moles of 
Moles of 
Mole ratio 
Therefore, the empirical formula for 
is 
.
Now, let's verify the statements:
I. Compound 
is Br2O3: Correct
II. Compound 
is 
: Correct
III. Compound 
is 
: Incorrect
IV. Compound 
is 
: Incorrect
