Calculate the no.of moles of gas present in the container of volume 10 L at 300 K . If the manometer containing shows 5m difference in the level ( density of glycerin =2.72 g/ml , density of mercury =13.6 g/ml)

d ( Hg ) = 5 * d ( glycerin )
d is proportional to P
so P ( glycerin ) = P ( Hg ) / 5
= 5 / 5 = 1 m = 100 cm
1 atm = 76 cm
P ( gas ) = 1 m + 1 atm= 176 cm = 176 / 76 atm
use
n = ( PV / RT )
n = ( 176 / 76 ) * 8 / 0.0821 * 300
n = 0.94 mole
