Answer:

#"Molality"="Moles of solute"/"Kilograms of solvent"#, and #"molality"# is often represented by lower case #m#.

Explanation:

And here, for your problem, we are at a loss as to how to proceed.

i.e. #"molality"=((15*g)/("molar mass of solute(?)"))/(0.500*kg)#. So we need to know #"molar mass of solute"# BEFORE we quote a figure in #mol*kg^-1#.
