Question

How much energy is required to vaporize 158 g of butane that has already been brought to its boiling point, if its AHvap is 2

Answer 1

Answer #1

Answer:-

Firstly from the given mass and molar mass , moles are calculated then using enthalpy of vaporisation, energy is calculated.

The answer is given in the image,

Answer: mang but one = 1588. Molar mass = 58 g/mol moles of Butane = meets molarmals 158 58 2.72 mol Alvap = 24.3 kJ/mol. . E
