Answer 2

Answer:

helium

Explanation:

Given,

hydrogen = 1g

helium = 4g

nitrogen = 7g

oxygen = 8g

Now,

mole of hydrogen = 1/2 mole

mole of helium = 1mole

mole of nitrogen = 1/2mole

mole of oxygen = 1/2mole

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.
