Answer:
Moles = 10.625 mol
Explanation:
Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,
Molarity = Moles / Volume of Solution ----- (1)
We can also rearrange this equation in terms of moles as,
Moles = Molarity × Volume of Solution ------(2)
Data Given;
Molarity = 4.25 mol.L⁻¹
Volume = 2.50 L
Now, putting value of Molarity and Volume in eq. 2,
Moles = 4.25 mol.L⁻¹ × 2.50 L
Moles = 10.625 mol
