The molarity of a solution prepared by diluting 2.67 g of NaOH to 100.0 mL in a volumetric flask is?
What is molarity of a solution of NaOH prepared by diluting 20.00 mL of 6.0 M NaOH to 500.0 mL? Why can we not calculate the actual molarity of the NaOH solution as indicated in the problems above? Why is an indicator required in the reaction vessel? Which indicator is used?
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...
A stock solution of Cu2+(aq) was prepared by placing 0.9157 g of solid Cu(NO3)2∙2.5 H2O in a 100.0-mL volumetric flask and diluting to the mark with water. A standard solution was then prepared by transferring 2.00 mL of the stock solution to a second 25.00-mL volumetric flask and diluting to the mark. What is the concentration (in M) of Cu2+(aq)in the stock solution? What is the concentration (in M) of Cu2+(aq)in the standard solution?
