Hi,

I'm trying to understand how to explain what the molal boiling point constant is, from interpreting the units (using an example) K_b =3,62K*kg*mol^-1 I would say "One mole of particles are heated up by 3,62kelvin per kg?"
but something feels wrong abou saying it that way. Can someone help me interpret the fraction k*kg/mol ? How do you say say it correctly in words?

Interpreting the units is a risky business, how do you interpret m/s2?

Kb is K/molality - change in the boiling point per molal concentration of solute.
