You are right.
>>But I do remember a problem where e.g. 1 mole was divided by 50 ml and the resulting unit was mM...is this right?
Here the question is whether 1 mole is quantity (solute) or concentration (solution). If it is quantity, you add 1 M solute into 50 ml solvent, you will get a 20 M solution (1 M / 0.05L = 20 M/L). If it is concentration, you have to give the amount to calculate the final concentration.
