What is the molar concentration of a solution of KF prepared by taking 37.5 mL of 0.442 M KF and diluting to a final volume of 500.0 mL with distilled water?
-
(volume of concentrated)(concentration of concentrated) = (volume of dilute)(concentration of dilute)
(37.5 ml)(0.442 M) = (500.0 ml)(x)
x = (37.5)(0.442) / (500.0)
x = 0.03315 M
(37.5 ml)(0.442 M) = (500.0 ml)(x)
x = (37.5)(0.442) / (500.0)
x = 0.03315 M
