If  16.8 ml  of the analyte h2c2o4  (oxalic acid) is titrated with  0.501 m  koh to  13.54 ml, determine the mass of the analyte.

What is the mass of 0.46 mil of mgcl2

)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.

This statement about matter and its behavior is best classified as a
