Question

A sample contains 22 gms of carbon dioxide. This is equal to:

• A. One mole of carbon dioxide
• B. Half mole of carbon dioxide
• C. Two moles of carbon dioxide
• D. One molar volume of carbon dioxide

Answer 1

The correct option is B

Half mole of carbon dioxide

44 g is equal to 1 mole of carbon dioxide

Molecular weight of $C{O}_2$= atomic weight of C + 2(atomic weight of O) =44 gm

Therefore, 22 g is equal to half mole of carbon dioxide.
