Given:
The molecule is Carbon dioxide.
To Find:
The mass of Carbon dioxide containing 8 grams of oxygen.
Solution:
Molecular Mass of Carbon dioxide.
= (12 + 2) x 16
= 12 + 32
= 44 g
It is clear that 32 g oxygen is present in 44 g Carbon dioxide.
Therefore,
8 g will be present in
= 44/11
= 11 g of Carbon dioxide.
The mass of Carbon dioxide containing 8 grams of oxygen is 11 grams.
