Answer» tion:Mass of empty density BOTTLE, M1 = 30 gramsMAss of bottle and water, M2 = 75 gramsMass of LIQUID and liquid x, M3 = 65 gramsMass of water = M2 – M1 = 45 gramsa) Volume of density bottle = Mass of water = 45 gramsb) Density of liquid x, D = mass of liquid/mass of water = 35/45Mass of iquid = M3 – M1 = 65 – 30 = 35 gramsD = Mass of liquid/mass of water = 35/45 = 0.77 grams/cm3c) Mass of water in the density bottle = 75 – 30 = 45 gramsTherefore, the volume of water in density bottle = 45 ccMass of the liquid WHOSE volume is equal to the density bottle = 65 – 30 = 35 gramsTherefore, relative density of the liquid = mass of 45 cc of liquid/mass of 45 cc of water = 35/45 = 7/9 = 0.77I think by this example u can find answer easily |
