Detailed explanation-1: -When 500 ml CO2 gas is passed through red hot charcoal the volume becomes 700 ml .
Detailed explanation-2: -Thus 0.0806 moles are present in 1 L of solution. This corresponds to 0. 086×44=3. 52g.
Detailed explanation-3: -At room temperature, the solubility of carbon dioxide is about 90 cm3 of CO2 per 100 ml water (cl/cg = 0.8). Any water-soluble gas becomes more soluble as the temperature decreases, due to the thermodynamics of the reaction: GAS (l) GAS (g).
Detailed explanation-4: -Pressure is also affected by the volume of the container. If the volume of a container is decreased, the gas molecules have less space in which to move around. As a result, they will strike the walls of the container more often, and the pressure increases.
