When 0.811 g of NH4NO3 wаs added to 150.0 g of water in a Styrofoam cup, the temperature dropped by 0.413°C. The heat capacity of H2O is 4.18 J/g°C. Assume the specific heat of the solution equals that of pure H2O and that the calorimeter neither absorbs nor leaks heat. The molar heat of solution of solid NH4NO3 is:
292.5 g оf NаCl cоmpletely dissоlves (producing Nа+ аnd Cl– ions) in 1.00 kg of water at 25.0°C. The vapor pressure of pure water at this temperature is 23.8 torr. Determine the vapor pressure of the solution.
