A) they (somewhat foolishly) only did one experiment: 1) they pipetted 25.0 ml into a pre-weighed erlenmeyer flask (mass flask plus stopper = 56.632 g) and obtained the mass of the flask, stopper, and liquid as 79.524 g. the stencil on the side of the pipet states the uncertainty as± 0.05 ml and the documentation for the analytical balance says its uncertainty is ± 1 mg. calculate the density of the liquid and either the relative uncertainty or the absolute uncertainty in the density obtained
