Answer:

3.1125L

Explanation:

Formula-

n=W/M

(W=mass given

M=Molecular mass)

PV=nRT

PV=WRT/M

V=WRT/PM

(P is pressure

V is volume

n is no. of moles

R is constant

T is temperature)

T should be in Kelvin

K=C+273

(where K is temperature in Kelvin

and C is temperature in Celsius)

K=27+273

K=300K

M of N2= 14+14=28g

V=WRT/PM

V=7×0.083×300/2×28

V=0.083×150/4

V=0.083×75/2

V=6.225/2

V=3.1125L
