The fluorocarbon compound c2cl3f3 has a normal boiling point of 47.6 °c. the specific heats of c2cl3f3(l) and c2cl3f3(g) are 0.91 j/g. k and 0.67 j/g. k, respectively. the heat of vaporization for the compound is 27.49 kj/mol.
calculate the heat required to convert 75.0 g of c2cl3f3 from a liquid at 11.50 °c to a gas at 80.30 °c.

The heat required to convert 75.0 g of from a liquid at 11.50 °C to a gas at 80.30 °C is 15.103 kiloJoules.

Explanation:

1) Heat required to raise the temperature of fluorocarbon compound from 11.50°C to 47.6 °C=

Mass of fluorocarbon compound = m = 75.0 g

Specific heat of fluorocarbon compound ,c= 0.91 J/gK

Change in temperature =

2) Heat required to raise the change the state of of fluorocarbon compound from liquid to gas=

Mass of fluorocarbon compound = m = 75.0 g

Moles of fluorocarbon compound =

The heat of vaporization for the compound =

(1 kJ= 1000 J)

3) Heat required to raise the temperature of fluorocarbon compound from 47.6 °C to 80.30°C=

Mass of fluorocarbon compound = m = 75.0 g

Specific heat of fluorocarbon compound ,c'= 0.67 J/gK

Change in temperature =

The heat required to convert 75.0 g of from a liquid at 11.50 °C to a gas at 80.30 °C:
