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)}}](https://img.qammunity.org/2019/formulas/chemistry/college/cxaqnhxu4jepkzp2s1cjrg85f5zu7ch86u.png)
Given: Molarity of solution = 5.00 M
Volume of solution = 750 ml = 0.750 l
∴ 5 =
![\frac{\text{number of moles}}{.750}](https://img.qammunity.org/2019/formulas/chemistry/college/yw3qjrk6fxyxhcw08zlv0fb8gv8f1obs9q.png)
∴
number of moles = 3.75Answer: Number of moles of KOH present in solution is 3.75.
