Solution

Mass percent-

  • Mass percent is a way of expressing a concentration or describing part of particular mixture.
  • The composition of the solution can be expressed by mass percentage indicating the amount of solute present in the given mass of solution.
  • The solute value is expressed in mass or in moles.
  • For a solution, mass per cent is defined as solute grams per gram of solution, multiplied by 100 to obtain a percentage.

Effect of temperature-

  • When temperature increases, solubility starts increasing.
  • When temperature decreases, solubility starts decreasing.

Step I: Find total mass of solution

  • Mass of sodium chloride (NaCl as solute)= 36gm
  • Mass of water (H2O as solvent)= 100gm
  • Mass of solution =36+100 =136gm

Step II: Find concentration

  • Concentration= (Mass of soluteMass of solution)*100
  • Concentration= 36136*100
  • Concentration= 26.47%

Hence, concentration of given solution came out to be 26.47%.
