Sunscreen preparation contains 2.35% by mass benzoyl salicylate. if a tube contains 6.0oz how many kilograms needed to manufacture 320 tubes

In what environment would mineral formation caused by high pressures and high temperatures most likely occur?

)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.
