solution to obtain 3.40 moles of KBr

1.42 L

Explanation:

Step 1:

The following data were obtained from the question:

Molarity of KBr = 2.40 M

Mole of KBr = 3.40 moles

Volume of solution = ?

Step 2:

Determination of the volume of the solution.

Molarity of solution is simply the mole of the solute per unit volume the of solution. It is given as:

Molarity = mole / Volume

Volume = mole / Molarity

Volume = 3.4/2.4

Volume = 1.42 L

Therefore, the volume of the solution is 1.42 L
