You have been given a 200.00 mL canister containing an unidentified gas. After accounting for the mass of the container, you determine the mass of the actual gas is 0.376 g. The pressure gauge on the canister reads 874 mmHg, and the temperature gauge reads 298.15 K. What is the identity of the gas? (R = 0.0821 L∙atm/mol∙K)
