Answer 2

Explanation:

Total pressure is 5 atm. The mole fraction of nitrogen is 0.8.

Hence,the partial pressure of nitrogen=P

T

×X=0.8×5=4 atm

According to Henry's law, P=KX

x is the mole fraction

K is the henry's law constant

P is the pressure in atm.

Substitute values in the above expression.

X=

1×10
