The van't Hoff factor for KCl is i= 1.85. What is the boiling point of a 0.50 m solution of KCl in water? For water, Kb = 0.51.(adsbygoogle = window.adsbygoogle || []).push({});

I have the equation which i beleive is (Delta Tb)= Kb x m x i ??

m= molality.... = .50 m

Kb is given 0.51

i is given 1.85

I have to have 5 sig figs and the answer i get is .47175, but that's not right supposedly. What I'm I doing wrong?
