Question

I 0.24 gram sample of compound of Oxygen and Boron and Boron was found an analysis to contain 0.096 gram of Boron and 0.4 gram of oxygen calculate the percentage composition of compound by weight

Answer 1

Percentage composition of compound by weight is 40% of boron and 60% of oxygen

Explanation:

First we have to consider the given information.

Given information:

Total mass of compound=0.24g

Mass of boron is=0.096 gram

Mass of oxygen in the compound=0.14 gram

so the percentage composition by weight of boron=$\frac{Mass of boron}{Total mass of compound} *100$

=(0.096/0.24)*100

=40%

Then consider oxygen compound:

The percentage composition by weight of oxygen=$\frac{Mass of oxygen}{Total mass of compound} *100$

=(0.14/0.24)*100

=60%
