Answer:
Molar concentration of potassium hydroxide = 0.27 mol / liter (Approx)
Explanation:
Given:
Moles of solute = 0.20 mol
Amount of solution = 0.75 liters
Find:
Molar concentration of potassium hydroxide = ?
Computation:
⇒ Molar concentration = Moles of solute / Amount of solution
⇒ Molar concentration of potassium hydroxide = 0.20 mol / 0.75 liters
⇒ Molar concentration of potassium hydroxide = 0.266666667 mol / liter
⇒ Molar concentration of potassium hydroxide = 0.27 mol / liter (Approx)
