A 2.0 M solution of LiF had 4.00 moles of LiF added to a solvent to make it. What is the volume of this solution?

A. 2 L

B. 3 L

C. 6 L

D. 8 L

2 L

Explanation:

From the question given above, the following data were obtained:

Molarity of LiF = 2 M

Mole of LiF = 4 moles

Volume =?

Molarity of a solution is simply defined as the mole per unit litre of the solution. Mathematically, it is expressed as:

Molarity = mole / Volume

With the above formula, we can obtain the volume of the solution as shown below:

Molarity of LiF = 2 M

Mole of LiF = 4 moles

Volume =?

Molarity = mole / Volume

2 = 4 / volume

Cross multiply

2 × volume = 4

Divide both side by 2

Volume = 4/2

Volume = 2 L

Therefore, the volume of the solution is 2 L.

c is the answer because when something is left after something evaporates that shows the chemical change.

the answer is b. dilution
