Experimental data showed thatthe freezing point depression of water in solution was –2.6°C when 1.0 g of glucose was dissolved in 10g of solvent. Calculatethe expected freezing point for such solution and compare the expected freezing point to the value found experimentally. Give aplausible explanation for any discrepancies. (M.W. of glucose= 180.16g/mol; i=1). Show all your work.Calculate the molar volume of the liquid and the vapor (both saturated) using the Redlich-Kwong (modified by Soave) (SKR) equation for the following cases: Propane at 40° C with saturated pressure = 13.71 bar. n-Butane at 100°C wiwth saturated pressure = 15.41 bar. Isobutane at 90° C with saturated pressure = 16.54 bar. Chlorine at 60° C with saturated pressure = 18.21 bar.

A gaseous sample of molecules, with a molar mass of 87.9 g/mol, is contained in a cylinder at a temperature of 362. K and pressure of 101.9 kPa. The collision cross section of a molecule is 0.73 nm2 The collision freqency, z, of the gas under these conditions is ____________ s-1.4.00 mol of perfect gas atoms with C p,m= 25 R is initially at 100.0 kPa, 100.0 dm3. It is heated to 150.0 dm3 at constant pressure and then heated to 150.0 kPa at constant volume. Calculate W, Q, ΔU and ΔH for this process.The molecular weight of two components A and B of a gas mixture are 24 and28 respectively. The molecular weight of gas mixture is found to be 30.

The oxyacetylene apple and the period of the oxyacetylene car company and bicycles made this good represent well. In an attempt to find a route to acetylene other than through calcium carbide, a Prest-O-Lite sponsored research by George O. Curme of the Mellon Institute in Pittsburgh. Ethylene research was directed towards converting gases for refining petroleum methods, led to more polyethylene material for acetylene production. Viewed from today's perspective, the Curme route to petroleum-based ethylene ranks as an important discovery. However, this was not the case at the time, because ethylene had almost no use before 1920. Curme's second major contribution was the research he carried out to see what useful products he could make with ethylene. The first was ethylene glycol, which became Prestone antifreeze. Others follow and now ethylene is evidently the most…When you determined the MW of a volatile liiquiid using the Erlenmeyer flask with the aluminum foil cap & the pinhole, explain briefly how you were able to obtain: -Mass of the vapor - Volume of the vapor -Pressure of the vapor - temperature of the vapor B) Calculate the MW of iodethane, a volatile liquid, given the following data obtained from the experiment in 12A, given that PV=nRT (R= 0.0821 L.atm.mol-1.K-1) Mass of residual liquid = 1.6384 g Pressure = 745.6 torr Volume of vapor = 327.8 mL Temp. of vapor = 100.0 C
