Astudent would like to prepare a 0.010 m solution from a 1.0 m stock solution with minimal error.
the student can choose to do a one-step dilution that uses a 10-ml transfer pipet and a 1000-ml volumetric flask or a two-step dilution using a 50-ml pipet and a 1000-ml volumetric flask for the first dilution, and a 100-ml pipet and a 500-ml volumetric flask for the second dilution. which method has the smallest overall relative uncertainty and what is the value?
o two-step dilution: 0.0020
o one-step dilution; 0.0010
o two-step dilution; 0.0014
o one-step dilution; 0.0020
