A stock solution of concentration 0.197 M is diluted in a two-step serial dilution. In the first step,56.00 mL of the stock solution is diluted to a final volume of 113.77 mL, and in the second step50.00 mL of the resulting solution is diluted to a final volume of 55.00 mL. What is theconcentration of the solution after the second dilution? Give your answer with 3 significant figures.
