I. PARTIAL MOLAR PROPERTIES The densities of aqueous solutions of copper (II) sulfate at 20 °C were measured as set out below. a. Plot the mol of CUSO4 versus volume of the solution in the range of the measurements. b. Determine the partial molar volume of CUSO4 for 1 mol of CUSO4 in solution. m CUSO4 (g) p (g/cm³) 52.6 1.051 111 1.107 176.5 1.167 250 1.230 where m(CuS04) is the mass of CUSO4 dissolved in 1000 g of water. MW(CUSO4)=159.6 g/mol Figure Q1. The mol of CUSO4 versus volume of the solution

A large tank filled with a mixture of methane and air at 102 kPa and 25 ⁰C is connected to another large tank filled with a different composition of methane and air also at 102 kPa and 25 ⁰C. The connection between the tanks is a tube with an inner diameter of 50 mm and length of 150 mm. The concentration of methane in one tank is 90 mole percent and in the other, 5 mole percent. DETERMINE: molar density of methane (kmol/m³)? CHOICES: 0.4875 4.1695 0.4010 0.04115
