A student performed the experiment described in this module. The 5.00-mL mass of the 2.15% percent by mass H2O2 solution used was 5.03 g. The water temperature was 230C, and the barometric pressure was 31.2 in. Hg. After the student immersed the yeast in the peroxide solution, she observed a 38.60-mL volume change in system volume. (1) Convert the barometric pressure to torr. (2) Obtain the water vapour pressure at the water temperature. (3) Calculate the pressure, in torr, exerted...

9. A student collected the following data: Mass of gas = 0.800 g, temperature of the water bath = 95.0°C, barometric pressure = 760.0 torr, and the volume of the flask = 250.0 mL. Later the student was told that one drop (0.050g) of water had been present in the flask during the experiment and it completely vaporized, contaminating the gas. (a) Calculate the apparent molar mass, that is, the molar mass the student would get if he did not...

A student follows the procedure described in the experiment and collected the following data: 25.5 mL of hydrogen gas collected, barometric pressure of 755 mm Hg, and a temperature of 298 K. Use the ideal gas law (PV=nRT) to answer the questions below. The R value is 0.08206 L atm / Kmol and our data must be in these units. The temperature is given in Kelvin, so no conversion is needed. But the hydrogen gas volume and pressure need conversion...
