Homework Statement
This is not a textbook question.
Henry's Law states that:
p=kx
where p=pressure of gas
x=mole fraction of gas in solution
k= Henry's constant
and k=p/x
So, we can say that k tells us the pressure of gas per unit x.
Which means k tells us the pressure of the gas when its mole fraction, x is unity.
But what does x=1 mean, since
x=no. of moles of solute/(no. of moles of solute + no. of moles of solvent)
if x=1
then this means: moles(solute)>>moles(solvent)
Am I wrong?
The value of k for helium dissolved in water is 144.97
What does it mean?
Please explain...
