Calculate the molality of NIOS in the solution prepared by dissolving program in enough water to form 250 ml of solution

Answer 1

How many grams of the solute are dissolved?What's the program amount?
mols solute = grams solute/molar mass solute = ?
Then assume density of the solvent (H2O) is 1 g/cc which makes the mass 0.250 g.
then molality = mols solute from above/0.250 = ?
