Dilution of Chemical Equations

Question

A chemist makes 460.mL of aluminum sulfate Al2SO43 working solution by adding distilled water to 160.mL of a 0.300M stock solution of aluminum sulfate in water.

Calculate the concentration of the chemist's working solution. Be sure your answer has the correct number of significant digits. Put answer in M.

Answer 1

(160 ml)(0.300 M) = (460 ml)(x M)

x = 0.104 M (3 sig figs)
