When N2gas is passed through water at 293k. how many moles of N2 dissolve in 1litre water

7 milimoles of dissolve in 1 litre water.

Explanation:

Given:   gas is passed through water at 293K.

Assumption : exerts a partial pressure of 0.987 bar.

Take : Henry's constant = 76.8 Kbar

To find : Number of moles of   gas dissolve in 1 litre water.

According to Henry's law,

moles in 1 liter  of water =

Let n= moles of nitrogen

Total moles = 55.56+n

So,

Hence, 7 milimoles of dissolve in 1 litre water.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the correct answer would be d. hope this !
