Report your answer to 3 significant figures in scientific notation (example: 1.23E+4) unless stated otherwise. DO NOT include the units in your answer.1. Answer the following questions based on an aqueous 2.76 M potassium thiosulfate stock solution.(a) If 23.6 mL of the stock solution are diluted to 433 mL, what is the molarity (in mol/L) of the new solution?1.50×10-1 M
(b) If 19.2 mL of the stock solution are diluted to obtain a 0.648 M potassium thiosulfate solution, what is the volume (in mL) of the new solution?mL
(c) Determine the volume (in mL) of the original stock solution that must be used to prepare 485 mL of a 0.397 M potassium thiosulfate solution.6.98×101 mL
(d) Determine the volume of water (in mL) that was added to 28.9 mL of the stock solution to prepare a 0.519 M potassium thiosulfate solution.mL
(e) Determine the concentration (in M) of potassium ions in a solution prepared by adding 134 mL of water to 19.0 mL of the stock solution of potassium thiosulfate solution.M
