PARAGRAPH
med moles of hydrogen to form a mixture. Take molar mass of helium M1 = 4g and that of hydrogen M2 = 2g
The equivalent degree of freedom f of the mixture is​

Answer 1

Answer:

Mole fraction of He=

7

5

=0.714

Mole fraction of H

2

=

7

2

=0.285

The Poissin's ratio γ for He and H

2

are 1.659 and 1.412 respectively.

The Poissin's ratio γ for the mixture is 1.659×0.714+1.412×0.285=1.185+0.40=1.59
