Chapter 15, Problem 21A
Solution

(a)

Interpretation:

Molarity of NaCl solution have to be calculated.

Concept Introduction:

Composition of a solution can be defined by expressing its concentration. The concentrations of solutions can be expressed in different ways, which are involved in the quantity of solute and the quantity of solution or solvent. Various methods are used to describe the concentration of the solution quantitatively. Some commonly used quantitative concentration terms are percent by mass, percent by volume, molarity, molality and mole fraction.

Molarity: Molarity is defined as the number of moles of solute present in one litre of the solution In expression, Molarity of the solution=Numberofmolesof the solute Volume of the solution(inlitre)

Again Numberofmolesofsolute=MassofthesoluteMolecularweightofthesolute

Molarity of NaCl solution is 4.17 M.

  Molarity of the solution=Numberofmolesof the solute Volume of the solution(inlitre)

Data given: number of moles of NaCl = 0.521 mol

Volume of NaCl solution = 125 mL = 0.125 L

  Molarity of NaClsolution=NumberofmolesofNaCl Volume of NaClsolution(inlitre)Molarity of NaClsolution=0.521mole 0.125litre=4.17M
