A certain sample of coal contains 1% sulphur by weight . what is the weight of sulphur dioxide produced when $$ 2 \times 10^6 $$ kg of this coal is brunt?

The vapour pressure of a solution of a non-volatile electrolyte B in solvent A is 95% of the vapour pressure of the solvent at the same temperature. If the molecular weight of the solvent is 0.3 times the molecular weight of solute, the weight ratio of the solvent and solute are:

How much slurry obtained per hour?

Which one of the following has greater active mass 

The number of atoms in 7.4 moles of $$Fe$$ are:

1.5 g mixture of $$SiO_{2}$$ and $$Fe_{2}O_{3}$$ on very strong heating leaves a residue weighing 1.46g.The reaction responsible for loss of weight is: 

Two liquids A and B forms an ideal solution at temperature T . When the total vapour pressure above the solution is 400 torr, the mole fraction of A in the vapour phase is 0.40 and in the liquid phase 0.75. The vapour pressure of pure A and B respectively are:
