Molar concentration of 96 g of `O_(2)` contained in a 2 L vessel is:

A

16 `mol//"litre"`

B

1.5 `mol//"litre"`

C

4 `mol//"litre"`

D

24 `mol//"litre"`

Text Solution

Verified by Experts

The correct Answer is:
B
Molar conc. = `("no. of molar(mole)"O_2)/("volume(in litre)")`
Moles= `(96)/(32)=3`
Molar conc.= `3/2=1.5 mol//"litre"`
