Interpretation:
Molarity of KNO3solution has 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 methodsare usedto 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,
Again

Answer to Problem 23A
Molarity of KNO3solution is 1.99 M.
Explanation of Solution
Data given: Mass of KNO3= 45.3 gm
Volume of KNO3solution = 225 mL = 0.225 L
