Question

The mole fraction of helium in a saturated solution at 0°C is 1.2 x 10–6. Find the pressure of helium above the solution. Henry's law constant is 6.8 x 10–6 atm–1

Answer 1

Answer:

$P=5.67atm$

Explanation:

Hello there!

In this case, since the Henry's law is shown below:

$P=H/x$

Whereas x is the mole fraction, H the Henry's constant and P the pressure. In such a way, we plug in the aforementioned first two to obtain the corresponding pressure:

$P=\frac{6.8 x 10^{-6} atm^{-1}}{1.2 x 10^{-6}} \\\\P=5.67atm$
