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 - (x1/x2) X2/x1 1/x2 X1/x2 1 - (x1/x2) X2/x1 1/x2 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Pick out the wrong conversion formula for the conversion of weight units : 1 tonne = 1000 kg = 22.046 lbs None of these 1 U.S. ton = 907 kg = 0.907 tonne = 0.893 ton 1 ton = 2240 lbs = 1016 kg = 1.016 tonnes = 1.12 U.S. tons 1 tonne = 1000 kg = 22.046 lbs None of these 1 U.S. ton = 907 kg = 0.907 tonne = 0.893 ton 1 ton = 2240 lbs = 1016 kg = 1.016 tonnes = 1.12 U.S. tons ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. Mole fraction of water vapour in the product gases is about 0.67 0.40 0.33 0.19 0.67 0.40 0.33 0.19 ANSWER DOWNLOAD EXAMIANS APP
