2. Predict the concentration if the solution is diluted to a volume of 1 liter. Show the calculation of this concentration, include units in all your work.

The question is incomplete, the complete question is;

Predict the concentration if a 0.5 M solution, with a volume of 500 mL, is diluted to a volume of 1 liter. Show the calculation of this concentration, include units in all your work.

0.25 M

Explanation:

From;

C1V1 =C2V2

C1= initial concentration = 0.5 M

C2 = final concentration = the unknown

V1 = initial volume = 500 ml

V2 = final volume = 1 litre = 1000 ml

substituting values;

0.5 * 500 = C2 * 1000

C2 = 0.5 * 500/1000

C2 = 0.25 M
