The concentration of dye in Solution A is 20.926 M. A serial dilution is performed to make Solutions B and C. In the first dilution, 7 mL of Solution A is diluted with 12 mL water to make Solution B. Then, 2 mL of Solution B is then diluted with 1 mL of water to make Solution C. What is the concentration of dye in Solution C? Provide your response to three significant figures in units of molarity.

a) What is the resulting nitrate ion concentration of the diluted solution if 24.00 mL of a 0.514 M sodium nitrate solution is diluted to a total volume of 350.00 mL? Note that this problem is asking for the concentration of the ion (after the salt dissolves) and not the concentration of the salt. Enter units. b) What is the resulting ammonium ion concentration of the diluted solution if 50.00 mL of a 0.572 M ammonium carbonate solution is diluted...
