(a) Show that s, the density of a slurry made up by combining a solid and a liquid is given by n=2x1+1(1x1)12 Where 1 is the density of the solid 2 is the density of the liquid x1 is the mass fraction of solids in the slurry Assume that the volumes are additive i.e. the volume of the slurry is the sum of the volume of solid and the volume of liquid. ( 7 marks) (b) Calculate the mass fraction of solid in an aqueous slurry having a density of 1.25gcm3 and the solid has a density of 3.0gcm3. The density of water is 1gcm3. (3 marks) May 2012
