Mass of solvent benzene = W 1 = 39 g Molar mass of benzene = 78 g mol-1. Question 2. 5.8 g of a non-volatile solute was dissolved in 100g of carbon disulphide (CS 2). The vapour pressure of the solution was found to be 190 mm of Hg. Calculate the molar mass of the solute. Given the vapour pressure of pure CS 2 is 195 mm of Hg (Molar mass of CS When 10 g of benzene (molar mass = 78 g / mol) are reacted with 9. mL of concentrated HNO3 (16 M) and 9 mL of H2SO4 (18 M), 8.1 g of nitrobenzene (molar mass = 123 g / mol) and 1.2 g of an unknown compound having a high boiling point. The molar mass of unknown molecular compound is determined using freezing point depression.

Benzene molar mass

• CH4 + C6H6 = C6H5CH3 + H2. The molecular weight of benzene is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be: 78.11184 · g mol The exact term of the above molecular weight is “molar mass”, which is based on the atomic mass of each element.
