1. You are required to prepare 0.56 M of NaCl for an experiment. Determine the amount of Naci (in gram) required if you only have 350 ml of distilled water. 2. Given that there is 0.04% by volume of CO2 in the air, determine the solubility of CO2 in water at 25 °C and 1 atm (ky for CO2 in water at 25 °C = 29.76 atm/(mol/L)). Formula: n = m/M Sgas...

The enthalpy of solution of KBr in water is about +198 kJ/mol (endothermic). Nevertheless, the solubility of KBr is relatively high. Explain why. A sample consisting of various gases contains 3.5*10^-6 mole fraction of radon. This gas at a total pressure of 36 atm is shaken with water at 30 degree C. Assume that the solubility of radon in water with 1 atm pressure of the gas over...
