摘要: The SEC and VPO behaviour of hydroxyl-terminated polybutadiene resins was investigated using toluene as solvent and polybutadiene and polystyrene as standards. The results show that molar mass obtained depend on the nature of the standards used in the calibration, specialy in SEC analysis....
Estimate the vapor pressure lowering and the osmotic pressure at 293.15 K for an aqueous solution containing 50.0 g of sucrose (M2 = 0.3423 kg·mol−1) in 1 kg of water. At this temperature, the density of pure water is 0.99729 g·cm−3 and the vapor pressure is 2.33474 kPa. Compar...
The mass concentration of species i in phase j is given by: (9.25)cij=ρiσij The molar concentration of species i in phase j is given by: (9.26)Cij=cij/Mi The mass fraction of species i in phase j is given by: (9.27)wij=cij/ρi The density, ρ, and velocity, v, of a mix...
After 1.00 ml of water is completely vaporized to gas, how many milliliters of vapor are produced at standard temperature and pressure? (Density of water is 1.00 g/mL; molar volume of any gas at STP is 22.4 L/mol.) What is the molar mass, in grams, of...
Example 3: Calculation of solution density If you add 50 g of sugar to 500 mL of water, how do you calculate the density of the sugar solution? Given: Density of water = 1 g/mL Flow Rate Concentration 1. Mass (or weight) fraction & Mole fraction n i i x 1 1 and n i i y 1...
Like other molecules, water has a distinct specific heat capacity that describes the heat needed to raise the temperature by 1 unit for one gram of water. From the specific heat capacity of water, we can determine the molar heat capacity using the molar mass of ...
Determine the densities of oil, gas, and water phases (flash calculations). • Determine the specified type of mass rate. • Calculate density of the fluid mixture. • Compute interpolation values of valve coefficient as described in Section 7.6. • Determine the pressure differential across...
Finally, mass density data for glycerol/water mixtures at 20°C, 1 atm pressure are presented in Fig. 3d [33]. Neither the Rackett nor the COSTALD molar volume sub-methods reproduce the experimental data paricularly well; however, the volume additivity assumption comes close to matching the...
