Problem- Calculate the molar mass that would be obtained from the actul experimental data under the following conditions. The unknown is mehy propy ether (CH3OC3H7) which has the vapor pressure of 375.2 torr at room temperature, 20C. The volume of the flask is 135mL, the temperature of the bath is 100C, and atm pressure is 760 torr. The average "mlar mass" of ai is 29.0g/mol.
I need proficient help to solve the above problem
1.000 g sample of a metal chloride, MCl2, is dissolved in water and treated with excess aqueous silver nitrate. The silver chloride that formed weighed 1.286 g. Calculate the atomic mass of M.
A 1.00 g sample of D2O and H2O are reacted with CL2 and HCL and DCL are produced. Then they are diluted with H2O giving a volume of 1.00L. Then 25 mL of the solution are reacted with excess AgNO3 and 0.3800g AgCl precipitate formed.
At high temperature, cyclopropane is converted to propene, the materialfrom which polypropylene plastics are made. The reactionwas monitored and the data below was collected:
