In the laboratory you dilute 2.49 ml of a concentrated 6.00 m hydrochloric acid solution to a total volume of 50.0 ml. what is the concentration of the dilute solution?

Equation: M1V1 = M2V2

Where M = concentration & V = volume

Step 1: Write down what is given and what you are trying to find

Given: M1 = 6.00M, V1 = 2.49mL, and V2 = 50.0mL

Find: M2

Step 2: Plug in the values into the equation

M1V1 = M2V2

(6.00M) (2.49mL) = (M2) (50.0mL)

Step 3: Isolate the variable (Divide both sides by 50.0mL so M2 is by itself)

(6.00M) (2.49mL) / (50.0mL) = M2

Answer: M2 = 0.30M
