Balloons of 4L capacity are to be filled...

Balloons of 4L capacity are to be filled with Hydrogen at a pressure of 1 atm and 27°C from an 8L cylinder containing Hydrogen at 10 atm at the same temperature. The number of balloons that can be fdled is

A

20

B

18

C

40

D

38

Text Solution

Verified by Experts

The correct Answer is:
B
`P_1V_1 = P_L V_L , 10(8) = 1(V_2)`
`V_2 = 80 "lit" implies `.V. of gs into baloons
`= 80 - 8 = 72` lit
no. of balloons = `72/4 = 18`.
