A zinc metal sample containing zinc chloride as impurity was made to react with an excess of dilute hydrochloric acid at 27°C. Liberated hydrogen gas is collected at 760mm Hg pressure that occupies 780.0cm3 volume. If the vapour pressure of water at 27°C is 14mm Hg, what is the volume of H2​ at STP? The Standard pressure is 760mm Hg (molar volume of gas at standard temperature and pressure, STP = 22.4dm3)
Liquids $A$ and $B$ form and ideal solution in the entire composition range. At $350\, K$, the vapour pressures of pure $A$ and pure $B$ are $7 \times 10^3\, Pa$ and $12 \times 10^3\, Pa$, respectively. The composition of the vapour in equilibrium with a solution containing $40\, mole$ percent of $A$ at this temperature is
