Question
A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion. Ag+...
What mass of lithium phosphate is needed to prepare 287 mL of a solution having a lithium ion concentration of 0.337 M? Select one: a. 4.158 b. 11.2 8 C.3.248 d. 13.48 e. 3.738
(5 marks) A solution containing chloride ion was analyzed by the mL sample containing chloride ion was treated with 25.00 mL of 0.2500 M silver nitrate. The precipitated AgCl was removed from the solution by filtration, and 1.00 mL of 0.1000 M Fe3 was added to the filtrate in order to titrate excess Ag with SCN. A volume of 10.67 mL of 0.2380 M KSCN was required for solution to turn red colour. What is the concentration of chloride ion...

What is the molar concentration of sodium ion in a 200 mL solution prepared from 1.223 g of sodium phosphate (Na3PO4)? The molar mass of Na3PO4 is 163.94 g/mol.
25.00 g of potassium hydrogen phosphate (K HPO4) is dissolved in enough water to make 125.0 mL of a solution with a density of 1.22 g/mL. What is the concentration of the solution in % (m/m). % (m/v). molarity, mosM and mEq/L of the potassium ion? Note: K2HPO4 has a molar mass of 174.2g/mole. What would be the final molarity of the above solution if you were to dilute it by adding 175 mL of water?
