Answer:
Explanation:
Hello there!
In this case, we can identify the solution to this problem via the Dalton’s rule because the partial pressure of helium is given by:
Whereas the mole fraction of helium is calculated by firstly obtaining the moles and then the mole fraction:
Then, we calculate the partial pressure as shown below:
