Explanation:
It is known that,
Molar mass of Br = 80 g/mol
Molar mass of O = 16 g/mol
Molar mass of H = 1.09 g/mol
Molar mass of C = 12 g/mol
Now, total mass of the compound is calculated as follows.
[tex]x + 12x + m \times 16 + 80[/tex] = 161
13x + 16 m + 80 = 161
We assume that m = 1. Hence, the value of x will be as follows.
x = [tex]\frac{81 - 16}{13}[/tex]
= 5
As per the formula 12x = 12y
or, x = y = 5
Therefore, molecular formula of the given compound is [tex]C_{5}H_{5}BrO[/tex].
