Question

In the laboratory you dilute 3.28 mL of a concentrated 6.00 M hydrochloric acid solution to a total volume of 150 mL. What is the concentration of the dilute solution?

__________M

Answer 1

$V_1 = 3.28\text{ mL}\\ C_1 = 6.00\text{ M}\\ V_2 = 150\text{mL}\\ C_2 =\ ?$

Using the dilution formula,

$C_1V_1 = C_2V_2\\ 6.00 × 3.28 = C_2 × 150\\ 19.68 = C_2 × 150\\ C_2 = 19.68/150 = 0.1312\textsf{ M}.$
