The density of water is determined by measuring the mass of a known volume of water. if you determined the density of a 25-ml sample of water, how many significant figures should you report if you used a s instruments? (refer to table 1-2 for the instrument uncertainties.) (a) an analytical balance for measuring mass and a 25-ml pipet for the volume measurement (b) a centigram balance and a pipet (c) an analytical balance and a graduated cylinder (d) a centigram balance and a graduated cylinder
