    According to the question it is given that Osmotic pressure of A and B are equal therefore let us assume that the pressure of to be π Since the osmotic pressure for both A and B are equal then the temperature will also be equal and let it be T. Now, we know that , π = CRT = amount of solute x RT/ mass. of solute x volume of solution Mass of solute = amount of solute x RT / πV Case 1 : We have , amount of solute, w = 0.2 amount of solvent, w'= 200 ml = 0.2 L Now, Molecular mass of A = 0.2 RT / 0.2 π = RT/π Case 2 : We have, amount of solvent , w = 0.3 g amount of solvent, w'= 200 ml = 0.2 L Now, Molecular mass of B = 0.3RT/0.2π = 1.5 Rt /π Thus, molecular mass of A < Molecular mass of B

    Because heat always flow from high temperature to low temperature. So , temperature of ice when put in water is 0 degree Celsius but room temperature of water is around 25 degree Celsius . So heat flow from water to ice and that heat melts the ice and temperature of water falls and water become cold ,

    Current and time is given and charge=I×t..and then you get total charge and apply Q=ne, where e=1.6×10^-19c so you get n that is no. Electrons

    flow of electron in one sec=0.5
    time given= 2 hours
    = 2(3600)sec
    =7200 sec
    therefore, flow of electron in 2 hours= 0.5 x 7200
    = 3600
