Calculate the density of `N_(2)` gas at S.T.P. ?

A

`1.250 g//L`

B

`0.628 g//L`

C

`2.450 g//L`

D

`1.42 g//L`

Text Solution

Verified by Experts

The correct Answer is:
A
`d = (PM)/(RT)` , Substituting the values, `P = 1 atm, M = 28, R = 0.0821"lit". "atm"."Mole"^(-1) K^(-1)` and `T = 273 K. d =(1 xx 28)/(0.0821 xx 273)= 1.25078 gm // "litre"`
