please answer all. 1) when you have 2.0M solution of NaCl, what is the molarity of Na+ ion and Cl- ion? 2) If you have 2.0M solution of CaCl2, what is the molarity of Ca2+ and the molarity of Cl-ion in this solution? 3) Comparing molarity of Cl- ion in 2.0M NaCl solution and 2.0M CaCl2 solution, which solution has more Cl- ion? 4) Give formula of the two ions exist in a solution of 0.10M of Al(NO3)3 ? what...
Calculate the molarity of each of the following ions. 0.733 g Na+ in 150.0 mL of a NaCl solution. ___M 0.480 g of Cl– in a 150.0 mL of a NaCl solution. ___M 0.360 g of SO42– in 150.0 mL of Na2SO4 solution. ___M 0.290 g of Ca2+ in 150.0 mL of CaCl2 solution. ___M
When you are given a concentration for a compound, such as 1 M NaCl, it indicates the number of moles of formula units per liter (formula-unit concentration). By multiplying the formula-unit concentration by the number of ions per formula unit, you arrive at the ion concentration. For example, a 1 M solution of NaCl has a 2 M ion concentration (1 M of Na+ ions and 1 M of Cl− ions) because there are two ions per formula unit of...

1. You prepare a NaCl solution by dissolving making 250mL solution out of 0.1409 g of NaCl (MW = 58.443 g/mol). You use this solution to standardize a Hg(NO3)2 solution. The volume of Hg(NO3)2 needed to titrate 10 mL of NaCl is 4.017 mL what is the molarity of the a Hg(NO3)2 solution? Note: Hg2+ + 2 Cl → HgCl2 2. Using the Folin-Wu tungstic acid method you pipet 10 mL of a serum sample and precipitate the protein (Note:...
