Question

A compound was found to contain 14.34 % oxygen, the minimum molecular weight of the compound

Answer 1

minimum molecular weight it contains oxygen only

let M be the minimum molecular weight

14.34 %*M=16

M=1600/14.34

M=111.57

Answer 2

Answer: The minimum molecular mass of the compound is 111.57 grams.

Explanation:

We are given:

A compound having 14.34 % of oxygen.

This means that 14.34 grams of oxygen are present in 100 gram of compound.

We know that:

Mass of 1 oxygen atom = 16 gram

To calculate the minimum molecular weight of compound, there must be 1 oxygen present. So,

If 14.34 grams of oxygen is present in 100 gram of compound.

Then, 16 gram of oxygen will be present in = $\frac{100g}{14.34g}\times 16g=111.57g$

Hence, the minimum molecular mass of the compound is 111.57 grams.
