M is equals to 3 mole per litre mass of NaCl in one solution is equal to 3 into 5 to 8.5 is equal to 175. 5 gram mass of 1 solution is equal to mm into 1.25 is equal to 1250 gram of water and solution is equal to 1250 minus 175 point 5 is equal to 10 74.5 molality is equal to number of moles of solute a point mass of solvent in Kg 3 upon 1.07 for 5 kg is equal to 2.79
