10.0 cm3 of a gaseous hydrocarbon X were exploded with 100.0 cm^3 of oxygen (an excess). After cooling, the total volume of the gaseous mixture was 80.0 cm^3 . After treatment with KOH (aq), the volume of gas decreased to 40.0 cm^3 . All volumes were measured at the same temperature and pressure. Use this information to determine the molecular formula of X. Draw two possible structures for X.

Worksheet 8 (Intro) 8. A metal tank contains three gases: oxygen, helium, and nitrogen. If the partial pressures of the three gases the tank are 35 atm of O, 5.0 atm of N2, and 25 atm of He, what is the total pressure inside of the tank? 9. The partial pressure of oxygen gas in a mixture of oxygen and nitrogen gases is 1.02 atm. The total pressure of the mixture is 2.43 atm. Calculate the partial pressure of nitrogen...

A student devised an experiment to determine the molar mass of an unknown gas X. Firstly, he filled a glass gas syringe (accurate to ± 0.5 cm3 ) with 100 cm3 of air then placed a rubber seal over the nozzle and weighed the syringe. He then emptied the gas syringe, refilled it with 100 cm3 of the unknown gas X, replaced the rubber seal and reweighed the syringe. Finally, he measured the temperature of the room. He obtained the...

Brass is a metallic alloy of copper and zinc. The relative percentages of copper and zinc determine the properties of the brass; resistance to corrosion and malleability, for example, are dependent on the relative amounts of copper and zinc. The percentage of zinc within a sample of brass may be determined using the techniques encountered in this experiment. 1. A 0.3400 g piece of brass is allowed to react with hydrochloric acid at the base of eudiometer. The hydrogen gas...
