Calculate the concentration of a solution that contains 70.0 grams of KOH in 400 cm^3 of solution
Solution
Molarity = No. of moles of solute / Volume of solution in Liter
No. of moles of KOH = (70.0 g) / (56.11 g/mol) = 1.247 mol
Volume of solution = 400 cm3 = 0.4 Liter
Molarity = (1.247 mol) / (0.4 Liter) = 3.12 M
So, the concentration of KOH solution = 3.12 M
