Wo solutions were made, the first one was made by dissolving 2.27 g of Co(NO3)2 in 100.0 mL of water. Then, to make the second solution, 5.00 mL of this solution was added to a 250 mL volumetric flask, which was filled to the mark with water. What was the mola concentration of the Co(NO3)2 in the two solutions? First solution = i .124 Second solution = i .00248 eTextbook and Media I M M
