The number of moles of H2 in 0.224 L of ...

The number of moles of `H_2` in 0.224 L of hydrogen gas at STP (273 K, 1 atm) assuming ideal gas behaviour is

A

`1`

B

`0.1`

C

`0.01`

D

`0.001`

Text Solution

Verified by Experts

The correct Answer is:
C
Applying PV = nRT ,
`P=1 " atm " , V = 0.225 L , R 0.0821 " L atm K"^(-1) " mol"^(-1)`, T =2 73 K
`n = (PV)/(RT) = (1 xx 0.224)/(0.0821 xx 273) = 0.01`
