The right answer is (a) Molecular weight of C2H5OH = 24+5+16+1= 46Molecular mass of H2O = 18414g of C2H5OH has 414/ 46= 9 mole18g H2O has 18/18 = 1 moleMole fraction of water = n1/ n1 + n1 = 1 / 1+9 = 1 / 10 = 0.1

Write a short note on the formula of diesel, petrol and also CNG?
A lean natural gas is available at 18oC and 65 bars and must be compressed for economical pipeline transportation. The gas is first adiabatically compressed to 200 bars and then isobarically (i.e. at constant pressure) cooled to 25°C. The gas, which is
The extent of adsorption of a gas on a solid adsorbent is affected by the following factors: 1. Nature of the gas Since physical adsorption is non-specific in nature, every gas will get adsorbed on the
