Dichlorodifluoromethane (CCl2F2, 120.91 g/mol) is a refrigerant and aerosol spray propellant that is commercially known as Freon-12. What is the density of CCl2F2 at 878 torr and 32.0°C? a. 5.60 g/L d. 39.9 g/L b. 53.4 g/L e. 5.40 g/L c. 4.18 g/L
Homework Answers
Using, ideal gas equation :
Density, d = PM/RT
M = molar mass = 120.91 g/mol
P = 878 torr = 878/760 atm = 1.155 atm (1atm = 760 torr)
R = gas constant = 0.082 Latm/mol.K
T = 32°C = 32+273.15 = 305.15 K
Substituting values, we get :
Density, d = 1.155×120.91/0.082×305.15
= 5.6 g/L

Materials: NaOH MW = 40 g/mL, KHP - potassium hydrogen phthalate, KHC8H404, MW = 204.23 g/mol. Acetic acid, HC2H302, MW = 60.05 g/mol Part 1: Standardization of NaOH Assume 0.951 g of KHP is weighed and transferred to a 250 mL Erlenmeyer flask. Approximately 50 ml water is added to dissolve the KHP. Note that the exact volume of water is not important because you only need to know the exact number of moles of KHP that will react with...
