Determine the molarity of a solution of potassium chloride that is prepared by dissolving 1.4753 g of KCl in a 100-mL volumetric flask and filling it to the calibration mark with deionized water. Use a molar mass with at least 4 significant figures so that the number of SF in the calculated molarity is not limited. Show all calculations (including labeled conversion factors) and express the answer with the appropriate number of significant figures. According to the manufacturer, the volume...
A solution of sodium was prepared by dissolving 0.0309 g of NaCl in distilled deionized water and brought up to the mark in a 200 mL volumetric flask. 10.0 mL of this solution was diluted to 250.0 mL. What is the concentration (ppm) of sodium the final solution
What is molarity of a solution prepared by dissolving 4.65 g NaCl (FM = 58.44 g/mol) in enough water to make 275 mL of NaCl solution?
A stock solution was prepared by dissolving 0.593 g of pure ASA (molar mass = 180.2 g/mol) with NaOH solution and diluting with water in a 1000 mL volumetric flask. This was followed by pipetting 4.00 mL of the stock solution into flask A and 5.0 mL of the stock into flask B. Flasks A and B were each diluted to 20 mL mark of the volumetric flask. What are the concentrations, in molarity, of ASA in flasks A and...
