Answer #1

The real gas equation is

(P+a/V2 ) (V-b) = RT

However you have not provided the values of a an b.

Now ideal gas equation is

PV = nRT

P = ?

V =1L

R = 8.314

mass = 28.5 g

so moles = mass / mol wt = 28.5 / 2 =14.25

T = 293K

R= 0.0821 L?atm?K?1?mol?1

P = 14.25 X 0.0821 X 293 / 1 = 342.78 atm
