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?

During the experiment, can the crucible and lid be touched with bare hands? (Choose all correct answers) No. If the crucible is still hot, a student can burn his or her hand. Yes. Gloves can be slippery, making it more dangerous to wear them in lab. Yes. They are easier to transport to the balance room and bare hands do not introduce error into the experiment. No. Dirt and oils on hands can add to the mass of the crucible.
