Answer 2

Molarity is one of the method of expressing concentration of solution. Mathematically it is expressed as,
Molarity =
`\frac{\text{number of moles of solute}}{\text{volume of solution (l)}}`

Given: Molarity of solution = 5.00 M
Volume of solution = 750 ml = 0.750 l

∴ 5 =
`\frac{\text{number of moles}}{.750}`
∴ number of moles = 3.75

Answer: Number of moles of KOH present in solution is 3.75.
