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

`P=5.67atm`

Step-by-step 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=(6.8 x 10^(-6) atm^(-1))/(1.2 x 10^(-6)) \\\\P=5.67atm`
