Questiоn 12: Which оf the fоllowing methods for prepаring а 0.0050 M solution from а 1.0 M stock solution provides the smallest overall uncertainty? Explain your answer through calculations!!! (Hint: The uncertainty for the one-step dilution is provided in the problem, no calculation needed.) (a) A one-step dilution that results in a relative uncertainty of 0.004. (b) A two-step dilution that uses a 50mL pipet and a 1000mL volumetric flask for the first dilution, and a 10mL pipet and a 100mL volumetric flask for the second dilution. (10 points)
