Potassium chlorate upon heating melts at 355 °C and decomposes at 480 °C. In the presence of Mn02(s) catalyst, KC1O3(s) completely decomposes into O2(g) and KCl(s). However, Mn02(s) itself does not take part in the overall chemical reaction. In an experiment to determine the gas constant, 1.300 g of pure KC103(s) and 100. mg of MnO2(s) were mixed in a testube and heated over a Bunsen burner. The resulting O2(g) product was bubbled in distilled water that is at exactly 25 °C (or 298.15 K) and collected in a 100- mL eudiometer. The experiment was done under a barometric pressure of 755 torr. The vapor pressure of water vapor at 25 °C is 23.8 mmHg. After the reaction was completed, the contents of the testube containing the MnO2(s) catalyst and the KCl(s) product was weighed to be 1.285 g. The level of the liquid inside the eudiometer rests 1.36 cm below the water level in the reservoir. The graduation on the eudiometer (not shown here) indicates that the trapped gas is 88.57 mL. a.

A gas of unknown molecular mass was allowed to effuse through a small opening under constant pressure conditions. It required 72 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 27 s for 1.0 L of 02 gas to effuse. Calculate the molar mass of the unknown gas. (Remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 L; that is, rate and time are inversely proportional.) 367.1175859 X g/mol
