1. We have a solution of unknown substance dissolved in water at the temperature of 300 kelvin , this solution gives rise to osmotic pressure of 2.25 atm then calculate what will be the molality of the solution?
2. We have noted that water level rises to 62.4mL when a piece of metal of 48 grams is dropped into 50.0mL of H2O in a graduated cylinder. Determine the density of this metal?
