Question

. The molar heat of vaporization of acetone, C3H6O, is 30.3 kJ/mol at its boiling point. How many kilojoules of heat would be liberated by the condensation of 5.00 g of acetone?

Answer 1

2.61 kilojoules of heat would be liberated by the condensation of 5.00 g of acetone

Step-by-step explanation:

To convert grams into moles

`moles = grams * (1 mole)/(grams)`

We have 5.00 g acetone

`moles = 5 * (1)/(58.1)`

`moles = 0.0861`

Heat liberated = moles
`*` heat of vapourization

=0.0861 mol x 30.3 kJ/mol

= 2.61 kJ

Therefore, 2.61 kilojoules of heat would be liberated by the condensation of 5.00 g of acetone
