Answer:let us add 2.4 mL of water in 0.6 ml of coloring solutiontotal volume of solution = 2.4 + 0.6 = 3 mL therefore,0.6 mL of coloring solution now includes = 2.4ml of wateror1 mL of coloring solution includes = 4mL of water Hencemeasure 3 mL of coloring solution with water that is formedtherefore, this 3 mL will contain 0.6 mL of coloring solutionGiven:formula calls for 0.6 mL of a coloring solution10-mL graduate calibrated from 2 to 10 mL in 1-mL unitsNow,We want to use an aliquot technique to measure 0.6 ml of coloring solution.Because the calibrated graduate is used to measure 2ml to 10ml with 1ml as unit measure let us add 2.4 mL of water in 0.6 ml of coloring solutiontotal volume of solution = 2.4 + 0.6 = 3 mL therefore,0.6 mL of coloring solution now includes = 2.4ml of wateror1 mL of coloring solution includes = 4mL of water Hencemeasure 3 mL of coloring solution with water that is formedtherefore, this 3 mL will contain 0.6 mL of coloring solution
