Silver is measured in lab with water There was 12.24 ml of water in the cylinder, and it weighed 37.42 grams. Then silver was placed into the cylinder and the volume was 14.04 ml and the mass was 56.32 grams. what is the density and atomic volume

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
