Question

What is the molarity of a solution with 23 moles of solute, and 100 ml of a solvent?

Answer 1

Molarity is calculated by using following formula,

Molarity = Moles / Volume

Data Given:
Moles = 23 moles

Volume = 100 ml ÷ 1000 = 0.1 L

Putting values in eq. 1,

Molarity = 23 mol / 0.1 L

Molarity = 230 mol/dm³

Result:
When 23 mol of solute is dissolved in a solvent to make a solution of 100 ml, then it will have a Molarity of 230 mol/dm³.
