Find the molality of iodine in benzene if the mole fraction of iodine in benzene is 0.2
1 Answer
Gaurav Rathod
First I will tell you what us relation between molality and mole fraction it is like a formula and it will help you to solve such type of sums.The formula is:Mole fraction = molality / molality + 55.5So the answer to given question is 0.2 = molality / molality + 55.5 0.2 × molality + 0.2 × 55.5 = molality11.1/0.8 = molality Answer is 13.875— Gaurav Rathod
