Only answers needed!1. You have a stock solution of 16.0 M NH3. How many milliliters of this solution should you dilute to make 1000 mL of 0.300 M NH3?2. If you take a 11.5-mL portion of the stock solution and dilute it to a total volume of 0.600 L what will be the concentration of the final solution3. How many milliliters of 0.140 M HCl are needed to completely neutralize 58.0 mL of 0.108 M Ba(OH)2 solution?4. How many milliliters of 0.123 M H2SO4 are needed to neutralize 0.160 g of NaOH?5. If 55.6 mL of BaCl2 solution is needed to precipitate all the sulfate ion in a 754 mg sample of Na2SO4 what is the molarity of the solution?6. If 42.5 mL of 0.214 M HCl solution is needed to neutralize a solution of Ca(OH)2 how many grams of Ca(OH)2 must be in the solution?7. Indicate the concentration of each ion or molecule present in the following solutions:A. 1.9×10-2 M MgSO4B. 2.50×10-2 M C6H12O6C. A mixture of 45.0mL of 0.272M NaCl and 65.0mL of 0.0247M (NH4)2CO3. Assume that the volumes are additive.
