Stoichiometry A very dilute solution is prepared by dissolving 'x1' mole of solute in 'x2' mole of a solvent. The mole fraction of solute is approximately equal to X1/x2 1/x2 X2/x1 1 - (x1/x2) X1/x2 1/x2 X2/x1 1 - (x1/x2) ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The heats of vaporisation of CS₂, C₂H₅OH &H₂O are 26.8, 38.6 & 40.6 KJ/kg mole respectively. The order of decreasing inter-molecular forces in these liquids is H₂O > CS₂ > C₂H₅OH H₂O > C₂H₅OH > CS₂ CS₂ > H₂O > C₂H₅OH CS₂ > C₂H₅OH > H₂O H₂O > CS₂ > C₂H₅OH H₂O > C₂H₅OH > CS₂ CS₂ > H₂O > C₂H₅OH CS₂ > C₂H₅OH > H₂O ANSWER DOWNLOAD EXAMIANS APP
