1. Calculate the amount of grams of CuSO4 (nice blue crystals) required to make a 0.340 M solution in a 500 ml volumetric flask. 2. When 4.05 g of CuSO4 are added to a 250 ml volumetric flask, and it is filled half way with distilled water, and gently swirled until the crystals dissolve, and then enough distilled water is added so the meniscus is right at the mark on the neck, what will be the resulting concentration of the...

Substance s has Imax = 485 nm. Two 50 mL aliquots of an aqueous solution S are transferred to two different 100 mL volumetric flasks. 25.0 mL of 200.0 ppm S are added to the second flask. Both flasks are then diluted to 100.0 mL with distilled water. At 485 nm, the first flask has A = 0.589 and the second has A = 3.72. Calculate the concentration of S in the original solution. Select one: O A. 18.8 ppm...

0.6573 g of potassium iodate is dissolved and diluted to a volume of 100.0 mL. Then 25.00 mL of this stock solution is pipetted into a 100.0 mL volumetric flask which is filled to the mark with water. What is the concentration of the final standard solution in mol/L? Include units in your answer, and round the final answer to the correct number of significant figures.

Imported ceramic bowls are analyzed for toxic heavy metals such as cadmium since these metals can be leached from the ceramic by the food in contact with it. The amount of cadmium that can be leached from the bowl is determined by adding an acetic acid solution to the bowl for a 24 hour period, after which the cadmium concentration in the acidic leaching solution is determined. In one experiment, the cadmium concentration in an acidic leaching solution was analyzed...

in the preparation of the standard Beer's law curve, 5.00 mL, 10.00 mL, 15.00 mL and 20.00 mL of a 0.108 M stock solution of glucose were added to separate 50 mL volumetric flasks. Afterwards, each of the flasks was filled to the mark with distilled water and labelled A, B, C and D accordingly. What is the concentration of glucose in the flask C? Report your answer to 3 decimal places.
