What is the moleculare Mass of PABA. When 8.32g of PABA is dissolved in 150g of Chloroform. ?

Question

the boiling point of pure chloroform is 61.2 degrees Celsius; the boiling point elevation constant of chloroform is 3.63 degrees Celsius/m

Answer 1

Sorry but you forgot the boiling point of this solution

delta T = boiling point solution - 61.2

delta T = m x 3.63

so you can get m = delta T / 3.63

m = moles PABA / 0.150 Kg

so you can find moles PABA

8.32 g / moles = molecular mass
