If the volume of a solution is 25.6 L and its molarity is 8.20 M, how many moles of solute are dissolved?
210 mol
O the molar mass of the solute is required to calculate the moles
O 3.12 mol
O 0.320 mol

210 moles

Explanation:

From the question given above, the following data were obtained:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:

Molarity = mole /Volume

With the above formula, the mole of solute dissolved can be obtained as follow:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity = mole /Volume

8.20 = mole / 25.6

Cross multiply

Mole = 8.20 × 25.6

Mole = 209.92 ≈ 210 moles

Thus, the mole of solute dissolved in the solution is 210 moles
