Question

I need help with question or Part C and if you could please write it out so i can understand it?

The rest of the question is attached as i know you need to know the rest of the information to anwser the question....

The vapor pressure of CCl3F at 300 K is 856 torr.

Part A

If 11.5 gg of CCl3FCCl3F is enclosed in a 1.1 LL container, calculate the number of moles of CCl3FCCl3F in the gas phase.

Express your answer using two significant figures.

n gaseous CCl3F =

5.0×10−2

mol

0.0503 molmol was either rounded differently or used a different number of significant figures than required for this part.

Use the ideal gas law to find the number of moles of gas present in a 1.1 LL container at 856 torrtorr and 300 KK:

Part B

Part complete

Given your answer to Part A, will any liquid be present?

Yes

There are 8.37×10⁻² molmol of liquid present initially and 5.03×10⁻² molmol of gas present at equilibrium. So, yes, there will be liquid present because not all of the liquid went into the gas phase.

Part C

If so, what mass of liquid will be present?

Express your answer using two significant figures.

mm liquid CCl3FCCl3F = ?? g
