The partial pressure of CO2 in air at sea level is 0.239 torr. If the solubility of CO2 at this partial pressure and 25 °C is 0.034 M, calculate kH. What is the molarity of CO2 at Pco 7.60 torr. A solution contains a mixture of pentane (CsH12) and hexane (CsH14) at room temperature. The solution has a vapor pressure of 258 torr. Pure pentane has a vapor pressure of 425 torr and pure hexane has a vapor pressure of...
1. A solution is prepared by dissolving 20.2 mL CH,OH in 100.0 mL HO at 25 degrees Celsius. The final volume of the solution is 118.0 mL. The densities of CHOH and H,O are 0.782 g/mL and 1.00 g/mL, respectively. For this solution, calculate molality, molarity, mole fraction of each component and % by mass of each component. 2. A solution contains a mixture of pentane and hexane at room temperature. The solution has a vapor pressure of 258 torr....
