the equation would be

ΔT= Kb . molality . I

I have this problem where im asked to calculate the mass of solute based on that formula, im given T and kb, but to my understanding the units of Kb are °C/molality, which cancels out with the m of the equation, so can't get the mass. Can anyone explain what I'm doing wrong? classic case of teacher not explaining s#*$ so i have to learn in on my own
