we know that
PV=nRT
PV= Mass/Molar mass× RT
P× Molar mass = Mass / Volume
PM = dRT
1 × M= 1.59 × R × 295............(1)
Again, We know that
PM = dRT
X × M = 3.18 × R × 298
Subtracting M= 1.59× R × 298
Therefore,
X × 1.59 × R × 298 = 3.18 × R × 298
(cancel out R and 297)
Then,
X × 1.59 = 3.18
X = 3.18 / 1.59
