WebA solution of benzene (C_6H_6) and toluene (C_7H_s) is 24.0 % benzene by mass. The vapor pressures of pure benzene and pure toluene at 25 degree C are 94.2 and 28.4 … WebSo, each mole of the solution will have 0.5 moles of benzene and 0.5 moles of toluene. Now, we have, 1 mole of benzene (C6H6) = 78 gm . so, 0.5 mole of benzene = 78 x 0.5 = 39 gm. Similarly 0.5 moles of toluene (C6H5CH3) will be = 92 x 0.5 =46 gm. Now we know that weight % = mass of component / total mass of solution x 100
WebEmpirical Formula. The Empirical formula is the lowest whole number ratio of the elements in a compound. In (section 2.10), we discovered that benzene and acetylene have the same mass percent composition, and thus it is logical that they have the same ratio of elements to each other, that is, they have the same empirical formula.. For salts that do not have … WebLet the total mass of the solution be 100 g and the mass of benzene be 30 g. ∴ Mass of carbon tetrachloride = (100 - 30) g = 70 g.
