10g of nacl were added to 10ml of water. he resulting solution was diluted to be a final volume of 250ml.
Calculate the molarity of the solution.

My calculation
10g/58g/mol = 0.173M
0.173M/025L =0.689M

Given the density of the solution is 0.9864g/ml. Calculate the molality of the solution. The right answer 0.7233m/kg
