Lowering in vapour pressure is highest for

Q.

pH of a 0.1 M monobasic acid is found to be 2. Hence, its osmotic pressure at a given temperature T K is

Q.

A solution containing 8.6 g urea in 1 L was found to be isotonic with a 5% (weight/volume) solution of organic non-volatile solute. The molecular weight of latter  is

Q. If saturated vapours are compressed slowly temperature remain constant to half the initial volume the vapour pressure will: a) become four times b) becomes double c)remain unchanged d) becomes half Sir, in this question I applied ideal gas equation since temperature is constant then on decreasing the volume to half should double the vapour pressure.But the correct answer is " vapour pressure remains unchanged?

If saturated vapours are compressed slowly (temperature remaining constant) to half the initial volume, the vapour pressure will remain unchanged as the vapour pressure cannot be increased due to saturation. vapour pressure is only affected by temperature
