P= 74.2/76 atm
V=?
m=5.25 g
M = 28 g
T=273+26
T=299 K
PV=nRT
74.2/76 x V= m/M x 0.0821 x 299
V=5.25 x 0.0821 x 299 x 76 /74.2
V=4.71074201 L

We know that PV=nRT
So V=nRT
P
For n
n= w/M
So 5.35/28. (Mol. Wt. Of N2 is 28) and when it is not given then we take their gas not atom
T is taken in Kelvin. So 273+26=299
And pressure in atm 7.42/76
V=5.35×0.082×299×76.
74.2
=4.71.Answer
Answer=4.71 and this question is from book written by RC mukherjee pg no 16 qno 11
