Answer 2

Hey there,

Given that ,

Mass of compound = 0.24 g

Mass of B = 0.096 g

Mass of O = 0.144 g

Let's solve,

Composition of Boron (%) = Mass of B / Mass of Compound* 100

0.096/0.24*100

Composition of Boron (%) = 40%

Composition of Oxygen (%) = Mass of O / Mass of Compound*100

0.144/0.24*100

Composition of Oxygen (%) = 60%
