How many milliliters of a 10.6 M NaOH solution are needed to prepare 0.715 L solution of NaOH with a concentration of 0.550 M?

37.1mL

Explanation:

This is a simple dilution problem where you utilize the equation:

(C=Concentration, V=Volume)

C1V1=C2V2

10.6 (y) = 0.715x0.550 (Y is unknown because we are trying to find how much of the original solution we need to dilute to make the final solution)

The solve for y and you get

y = 0.0317 L but this is in L and we want mL so multiply by 1000 you get

y = 37.1mL
