During a lab experiment, an unknown gas was observed reacting violently when it caused heated steel wool to burst into flames. to help identify the unknown gas, one student suggested to find the molar mass.

A 0.5750 g sample of the gas was measured as having a volume of 343.3 mL at 102.9 kPa and 24 degrees celsius. Use this information to calculate the molar mass of the gas. And record your answer to two decimal places.
