Achemist takes 50-gram sample of sulfur powder that has a melting point of 115.2 °c. what is the melting point of a 100-gram sample of sulfur powder? 115.2 °c since melting point is an extensive property 115.2 °c since melting point is an intensive property double of 115.2 °c since melting point is an intensive property double of 115.2 °c since temperature is an extensive property

)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.
