The boiling point elevation equation is Delta Tb=Kb*m*i, where m stands for molality, not mass. It's a badly worded question, just throw it out.The Kb is 1.78 for 1 kilogram of aceton. What is the value of Delta Tb for 100 grams of acetone?
My calculation as follows:
Tb = Kb x mass x i Since aceton is non electrolytes, so i = 1, so TB = Kb x mass
100 g x (1.78 / 1000g ) so 0.178, but solution said 1.78 so I posted it here
