Question

How many moles of koh are contained in 750. ml of 5.00 m koh solution?

Answer 1

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.
