A135 g sample of carbon disulfide requires 43.2 kj of heat to vaporize completely. what is the enthalpy of vaporization for carbon disulfide? a. 1.77 kj/mol b. 24.4 kj/mol c. 76.2 kj/mol d. 0.320 kj/mol e. 3.13 kj/mol

Molecular weight of CS2 = 76.14 g

number of moles of CS2 = 
                                        = 
                                        = 1.773

Now, 1.733 mol requires 43.2 kj of heat to vaporize.
∴  1 mol will require  = 24.4 kj/mol

Thus, correct answer is option B

Dmight be the correct answer

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.
