Question

23 gram of salt is dissolved in hundred gram of water at 293K . What is the concentration of solution at this temperature

Answer 1

mass of concentration=mass of solute ×100/mass of solvent
=23×100/123=2300/123

Answer 2

23/123 × 100 using concentration of a solution= mass of solute / mass of solution ( mass of solute + mass of solvent ) × 100
