Before the introduction of chlorofluorocarbons, sulfur dioxide (entha; py of vapourization, 6.00 kcal/mol) was used in household refrigrators. what mass of so2 must be evoparated o remove as much heat as evaporation of 1.00 kg of ccl2f2(enthalpy of vapourization is 17.4 kj/mol)?
the vapourition reactions for so2 and ccl2f2 re so2 (i) ? so2 and ccl2f(i) ? ccl2f2(g), respectively

367 grams

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

Enthalpy of vaporization is the amount of heat released when 1 mole of substance is converted from liquid to gaseous state.

Given : Enthalpy of vapourization of = 17.4 kJ/mol

To calculate the number of moles, we use the equation:

1 mole of produces heat = 17.4 kJ

8.3 moles of produces heat =

Given : Enthalpy of vapourization of = 6.0 kcal/mol =   (1kcal=4.184kJ)

25.104 kJ heat is produced by = 1 mole of

144 kJ  heat is produced by = of

Mass of

Thus 367 grams  of must be evoparated o remove as much heat as evaporation of 1.00 kg of
