- Freon-12 CF-a, is commonly used as the refrigerant in cen- sal home air conditioners. The system is initially charged to a
pressure of 4.8 atm. Express this pressure in each of the fol-
lowing units (I at =
14.7 psi).
A. mm Hg
B. Torr
c. Pa
d psi

Step 1 of 3

To determine pressures in each of the different units, you need the below relations:

(a) To convert pressure in atmospheres to mm Hg, use the relation given by,

We have, initial pressure charged to the system is 4.8 atm. So, the pressure in mm Hg is  So, the pressure in mm Hg is.Freon-12 is used as a refrigerant in central home air conditioners. The rate of effusion of Freon-12 to Freon-11 (molar mass = 137.4 g/mol) is 1.07:1. The formula of Freon-12 is one of the following:

\mathrm { CF } _ { 4 } , \mathrm { CF } _ { 3 } \mathrm { Cl }, \mathrm { CF } _ { 2 } \mathrm { Cl } _ { 2 } , \mathrm { CFCl } _ { 3 } , \text { or } \mathrm { CCl } _ { 4 }. CF  4 ,CF  3Cl,CF  2 Cl  2 ,CFCl  3 , or CCl  4
