Stoichiometry MCQs

Measurement of the amount of dry gas collected over water from volume of moist gas is based on the

C_v for monoatomic gases is equal to(where, R = gas constant)

Applicability of Claussius-Clapeyron equation is subject to the condition that the

The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.?

Specific gravity on API scale is given by the relation(where, G = specific gravity at 15.5°C).

1 kg/m² is equal to __________ mm water column.

The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. The temperature at which the above mixture will exert a pressure of one standard atm. is

Solutions having the same osmotic pressure are called __________ solutions.
