Calculate the molar concentration of sodium chloride solution if 500 ml of this solution contains 0.5 mol of sodium chloride.
1. The molar concentration of a solution shows how many moles of a substance are in 1 liter. This solution contains 0.5 mol / 0.5 L = 1 mol / L sodium chloride.
2. Find out the total amount of the substance in the solution:
24 l * 6 mol / l = 144 mol.
Now let’s calculate the molar mass of the substance:
2880 g / 144 mol = 20 g / mol.
