Q.
At 20∘C the solubility of N2 gas in water is 0.015g/L when the partial pressure of N2 is 580 torr. What is the solubility of N2 in H2O at 20∘C when its partial pressure is 800 torr?
At 20∘ solubility of N2 in water is 0.015g/L.
When partial pressure is 580 torr.
According to Henry’s law m∝p m=KHp 0.015=KH×580 KH=0.015580
For the solubility of N2 in at 20∘C =KH800=580800×0.015 =0.0207g/L
