As the result of a chemical reaction, 48.3 g of methane CH4 gas is produced. Using the ideal gas law, determine the pressure of the gas produced when the volume is 16.0 liters and the temperature is 31°C.
Derive an expression for the compression factor of a gas that obeys the equation state p(V-nb) = nRT, where b and R are constants. If the pressure and temperature are such that Vm = 10b, what is the numerical value of the compression factor
A method for measuring organic carbon in seawater consists of oxidation of the organic materials to CO2 with K2S2O8, followed by gravimetric determination of the CO2 trapped by a column of NaOH-coated asbestos.
a sample of gas has an initial volume of 13.8l at a pressure of 1.26 atm if the sample is compressed to a volume of
