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)

A4.25 %w/v solution (4.25g per 100.0 mL) of starch in water was found to have an osmotic pressure of 82.7 mmHg at 303.6 kelvin. Calculate the average molar mass of the starch used, taking 1.00 atm = 760.0 mmHg. The value of the gas constant, R , is 0.0821 L atm K-1 mol-1. Present your answer as a numerical value only, to 3 significant figures in the form x.xxEx.
