Question

What volume of concentrated hydrochloric acid (12.0 M HCl) is required to make 2.0 liters of a 3.0 M HCl solution?
A) 5.0 liters
B) 0.24 liters
C) 0.50 liters
D) 6.0 liters

Answer 1

Have you used this equation before?
\( M_1 V_1 = M_2 V_2 \)

Answer 2

No I haven't

Answer 3

Or perhaps instead of M's it was C's: \(C_1 V_1 = C_2 V_2 \).
But, that is the equation we should use in this problem. There may be more information on it here: http://www.chemteam.info/Solutions/Dilution.html

Basically, the product of the molarity and volume of the concentrated solution equals the product of molarity and volume of a diluted solution.
We would substitute: Molarity1 = 12 M, Volume1 = unknown. Molarity2 = 3 M, and Volume2 = 2 L.
\( 12 \times V_1 = 3 \times 2 \)
And solve for V_1.
