One of the nobles gase of group was isolated in 1894 by allowing a large volume of air to react with magnesium so that the only noble gas, contaiminated with tracs of other noble gases, remainded A 32.0 mL sample of this gas weighed 0.054 g at 9.0 degrees celcius and 748 torr. Determine the apparent molecular weight of this monatomic gas. The traces of the other gases are negiligble.

Which gas it is?

19.9 g/mol; He

39.7 g/mol;Ar

20.1 g/mol; He

39.8 g/mol; Xe

83.4 g/mol;Kr
