Which contains more number of molecules?

A

1 mole of carbon dioxide

B

4g of hydrogen

C

33.6 litres of oxygen at STP

D

6g of helium

Text Solution

Verified by Experts

The correct Answer is:
B
1 Mole of `CO_(2) = 6.023xx10^(23)` molecules
4 g hydrogen `=(4)/(2)xx6.023xx10^(23)`
`=2xx6.023xx10^(23)` molecules
33.6L of oxygen at STP
`=(33.6)/(22.4)xx6.023xx10^(23)`
`=1.5xx6.023xx10^(23)` molecules
6g helium = `(6)/(4)xx6.023xx10^(23)`
`=1.5xx6.023xx10^(23)`
`=1.5xx6.023xx10^(23)` molecule
