# Problem: The vapor pressure of CCl3F at 300 K is 856 torr. If 12.5 g of CCl3 F is enclosed in a 1.2 L container, calculate the number of moles of CCl3F in the gas phase.

###### FREE Expert Solution

We are asked to calculate the number of moles of CCl3F in the gas phase.

Use the ideal gas law :

Convert the values need to be consistent with  R.

R = 0.08206 L-atm/mol-K

V = 1.2 L

T = 300 K
