Stu and noke are working with a red food coloring, red #40. the stock solution has a concentration of 0.0880 m dye. noke want to makes a concentration of 0.0088 m, exactly one tenth of the original red dye solution strength. what volume of the original 0.0880 m solution should she measure into a 100.0 volumetric flask, to be diluted with water up to the line of the flask? (3 significant digits, unit ml)
2)stu dilutes the stock 0.0880 m red dye solution (same as the previous question by measuring 25.00 ml with a pipet into a 100.0 ml volumetric flask and then adding water up to the line on the flask. calculate the new concentration of his diluted solution. (round to 3 significant digits, unit m)
