Molarity is one of the method of expressing concentration of solution. Mathematically it is expressed as,
Molarity = [tex] \frac{\text{number of moles of solute}}{\text{volume of solution (l)}} [/tex]
Given: Molarity of solution = 5.00 M
Volume of solution = 750 ml = 0.750 l
∴ 5 = [tex] \frac{\text{number of moles}}{.750} [/tex]
∴ number of moles = 3.75
Answer: Number of moles of KOH present in solution is 3.75.
