Question

mole fraction of H2 in a 2g mixture of H2 and he is 0.5.thus helium present in the mixture in grams is​

Answer 1

1gm of hydrogen, 4gm of helium,7gm of nitrogen,8gm of oxygen

Now,

Given mole of hydrogen

=1mole

mole of nitrogen=

28

1

mole

mole of oxygen=

32

8

=

4

1

mole

We know according to ideal gas equation

P∝n , P=pressure, n=no of moles

Therefore,the gas having highest no of moles will have height partial pressure.

hence helium will have highest partial pressure.
