Question

The mass of a sample of solution is 6.12 ± 0.01 g and the volume is 6.5 ± 0.5 mL. a) What is the absolute error in the mass? What is the relative error in the volume? b) Calculate the error in the density ε(d) and report the density of the sample in the form: d ± ε(d). c) If you estimate that the relative error in the mass is negligible compared to the relative error in the volume, will your reported error in the density, ε(d) change? Is it always possible to make this type of approximation?
