PRE-EXPERIMENTAL QUESTIONS 1. In an experiment, the mass of a given sample of ethene, C2H4, gas was found to be 0.2805 grams. (a) If this mass occupied a volume of 314 cm3 at 370 K and 98,000 Pa then what is the density of the gas under these conditions? Answer in kg/m3 (b) What is the gram molecular mass of this gas? 2. Using the formula of ethene, calculate its gram molecular mass. How does it compare with the experimentally determined one?
