At 300 K, 36 g of glucose present in a litre of its solution has an osmotic pressure of 4.98 bar. The concentration at which osmotic pressure of the solution becomes 1.52 bar at the same temperature, would be:
1. | 0.06 M | 2. | 0.12 M |
3. | 0.08 M | 4. | 0.36 M |
The amount of CaCl2 (i = 2.47) dissolved in 2.5 litre of water such that its osmotic pressure is 0.75 atm at 27 °C is:
1. | 1.02 g | 2. | 4.35 g |
3. | 2.87 g | 4. | 3.42 g |
