A soap bubble is formed from `10^(-3)g` of soap solution. When it is filled with hydrogen of density `0.00009g//cm^(3)`, it floats in impure argon gas of density `0.00199g//cm^(3)`. What will be the excess pressure nearly in dyne per `cm^(2)`, of surface tension of soap solution is 12 dyne/cm. (Take `pi^(-1)=0.318`)
