6 moles of potassium permanganate (KMnO4) are dissolved in enough water to make a 3M solution. What is the volume of the solution expressed in mL.

2000 mL

Explanation:

Given data:

Number of moles KMnO₄ = 6 mol

Molarity of solution = 3M

Volume of solution in mL = ?

Solution:

Formula:

Molarity  = number of moles of solute / volume of solution in L

3 M = 6 mol / volume of solution in L

volume of solution in L = 6 mol/ 3 M

volume of solution in L = 2 L

Now we convert the L into mL:

1 L = 1000 mL

2 L × 1000 mL / 1 L

2000 mL

the answer is minerals.
