Assuming the same pressure in each case ...

Assuming the same pressure in each case calculate the mass of hydrogen requied to inflate a ballon to a certain volume `V` at `100^(@)C` if `3.5 g` helium is required to inflate the balloon to half the volume `V` at `25^(@)C` .

Text Solution

Verified by Experts

`Pxx V = (w)/(2) xx R xx 373`
(V is volume of ballon)
For He : `P xx (V)/(2) = (3.5)/(4) xx R xx 298`
`w_(H_2) = 2.8g` .
