## anonymous one year ago A mixture of He and Ne at a total pressure of 0.95 atm is found to contain 0.32 mol of He and 0.56 mol of Ne. The partial pressure of Ne is ___ atm

1. Rushwr

$P _{total} = P _{He} + P _{Ne}$ Partial pressure of a gas = molar fraction x total pressure

2. anonymous

How do i find the molar fraction?

3. Rushwr

Molar fraction = no. of moles of one component divided by the total no. of moles of all the compounds in the mixture

4. Rushwr

The molar fraction of Ne would be $\frac{ 0.56mol }{ (0.56 + 0.32)mol }$

5. anonymous

Awesome! so then i take that times 0.95?

6. Rushwr

yep
