0.1 mole of H\(_3\)PO\(_3\) is present in 500 mL of solution. The normality of it is:
At 300 K, the vapour pressures of A and B liquids are 500 and 400 mm Hg respectively. Equal moles of A and B are mixed to form an ideal solution. The mole fraction of A and B in vapor state is respectively.
Two statements are given below:
Statement - I: Liquids A and B form a non-ideal solution with positive deviation. The interactions between A and B are weaker than A-A and B-B interactions.
Statement - II: For an ideal solution, \( \Delta H_{\text{mix}} = 0 \), \( \Delta V_{\text{mix}} = 0 \).
The correct answer is
At \( T(K) \), two liquids A and B form an ideal solution. The vapour pressures of pure liquids A and B at that temperature are 400 and 600 mm Hg respectively. If the mole fraction of liquid B is 0.3 in the mixture, the mole fractions of A and B in vapour phase respectively are:
