Answer With Work Shown Please 1.A metal tank contains three gases: oxygen, helium and nitrogen. If the partial pressure of the three gases in the tank are 30 atm of O2, 10 atm of N2, and 20 atm of He, what is the total pressure inside of the tank? 2.The concentration of ions in seawater is approximately the same as that in a solution containing 3.0 g of NaCl dissolved in 200. g of water. Use this information and a predicted value for the van’t Hoff factor (i=2) to determine the freezing temperature (in oC) of the solution (assume ideal solution behavior). Kf of water= 1.86°C kg water/mol ion 3A solution of 2.00 g of a nonelectrolyte dissolved in 100.0 g of benzene is found to freeze at 3.00 °C. Assuming ideal solution behavior, what is the molar mass of this compound? Benzene: Fp= 5.5oC, Kf= 5.12oCm-1
