Dilution of Chemical Reactions

Question

A chemist makes 870.mL of silver nitrate AgNO3 working solution by adding distilled water to 160.mL of a 1.92molL stock solution of silver nitrate in water.

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

Answer 1

V1M1 = V2M2

(160 ml)(1.92 M) = (870 ml)(x M)

x = 0.353 M
