Pls help with all answer. Attempt Q-1 , Q-2 and Q-3 (with sub parts) . if you don't know then pls dont attempt. bcs i need all parts to be answer. I will definitely give a thumbs up. thanky you tutor
1. A 6.42% (w/w) Fe(NO3)3 solution has a density of 1.06 g/mL. A 21.70 mL of this solution was diluted with water to 50 mL in a volumetric flask. Calculate the concentration of the diluted Fe(NO3)3 solution in: a) % (w/v) b) Molarity c) Part per million 2. Describe how to prepare 500 mL of a solution that is 60.0 ppm in Clstarting with solid MgCl2. 3. A solution is prepared by dissolving 3.5725 g H3PO4 in 500 mL volumetric flask and diluting it to the calibration mark. Calculate: a) the normality of the H3PO4 solution. b) the concentration (ppm) of H+ ion in the solution.
