Answer:
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
Are you gonna list the ppl?
