Answer to Question #172335 in General Chemistry for Dori

Question

Please provide steps with an explanation

...

For ether at 1 atm:

Heat of vaporization = 85.45 cal/g

Boiling point = 34.60°C

Heat of fusion = 23.44 cal/g

Melting point = –116.3°C

Specific heat gas = 0.3489 cal/g°C

Specific heat liquid = 0.5545 cal/g°C

How many kcal of energy must be added to the sample to raise its temperature to 37.30°C? if  24.50 g sample of liquid ether is initially at 0.3000°C.

Energy added is .........kcal

Answer 1

(1)raise the temperature of the liquid to its boiling point

(2)vaporize the liquid at its boiling point and (3)raise the temperature of the resulting gas to the final temperature.

Energy added is 22.31kJ
