Making Potassium thiocyanate aqueous solution


Hey
I have to make 100ml of 2% Potassium thiocyanate aqueous solution.
There is no any information about molar mass so probably it refer to a standard solution 0.1 M KSCN.
Any info haw to make it is really welcome.

If you do not take in account a change in density, let´s say 100 mL = 100 g. There are 2 g of KSCN dissolved then. For 0.1M KSCN aqueous solution - there would be 0.972 g dissolved in 100 ml of solution. The change in density for the solution would not be so extreme to have difference one gram.. so it does not refer to a standard solution.
