1.	25g of Nacl is dissolved in 500ml of water. find the molality(m) of the resulting solution.
Answer» NACL dissolved in solvent = 25 gramvolume of solvent = 500 ml = 0.5 litreMolarity = ?here Nacl is SOLUTE and WATER is solvent moles of Nacl = 25 / 58.5 = 0.42 Molarity = no. of moles of solute/volume of sol(LIT)M = o.42 /o.5M = 0.84 mol/litre.thnks for asking .......
