Question

How many liters of solution are needed to make a 1.85 M solution containing 2.40 moles of KMnO4?

Answer 1

Answer:

Volume of solution L = 1.3 L

Explanation:

Given data:

Volume of solution needed = ?

Molarity of solution = 1.85 M

Moles of KMnO₄ = 2.40 mol

Solution:

Formula:

Molarity = number of moles / volume of solution L

1.85 M = 2.40 mol /  volume of solution L

now we will put the values.

Volume of solution L = 2.40 mol  / 1.85 M

          M = mol/L

Volume of solution L = 1.3 L
