6. Consider the determination of the molecular weight of a gas by measurement of the temperature, pressure, and volume of a known weight of the gas. The necessary data is given below: Mass of the gas =0.6044 + 0.0001 g

temerature =423.15 + 0.01 K

Pressure= 4.698 + 0.001 atm

Volume=248.2 + 0.1 mL

R= 0.0820575 Latm/molK (a) Calculate the molecular weight of the gas. Use significant figures. (b) Calculate the uncertainty in the molecular weight using the differential changes method and report the molecular weight together with the uncertainty. (c) What is the most likely identity of the compound being studied? Explain your reasoning.
