0.48 g of a sample of a compound containing boron and oxygen contains 0.192 g of boron and 0.288 g of oxygen. What will be the percentage composition of the compound?

A

60% and 40% B and O respectively

B

40% and 60% B and O respectively

C

30% and 70% B and O respectively

D

70% and 30% B and O respectively

Text Solution

Verified by Experts

The correct Answer is:
B
Mass of compound taken = 0.48g ltbr. Mass of boron in sample = 0.192 g
Mass of oxygen in sample = 0.288g
Percentage of B `=(0.192)/(0.48)xx100`=40%
Percentage of O `=(0.288)/(0.48)xx100=60%`
