Three samples of three different gases are listed in the table below. All the samples contain exactly 1 mole of gas and are at a temperature of 0.0°C. For each sample, decide whether the gas can be reasonably described as an ideal gas. If the gas isn't ideal, decide the most important reason why it isn't. sample A B C pressure (atm) 2.7 1.5 0.75 volume (L) 10.0 20.0 30.0 ideal? O yes O no O yes O no O yes O no If not ideal, the most important reason why not: O There are attractions between the particles. O The particles don't have zero volume. There are attractions between the particles. O The particles don't have zero volume. There are attractions between the particles. O The particles don't have zero volume. X Ś

Determine the molar mass of unknown gas if a sample weighing 0.389 g is collected in a flask with a volume of 102 cm³ at 97°C. The pressure of the unknown gas is 728 mmHg. O a. 187 g/mol O b. 112 g/mol O c. 121 g/mol O d. 31.6 g/mol O e. 8.28 X 103 g/mol ww

An ideal sample of carbon dioxide gas at 303 K and 0.457 atm occupies a volume of 3.10 L. If the gas is compressed into a smaller volume, while at the same time it is heated to a higher temperature, the final gas pressure: Could be higher or lower than 0.457atm, depending on the final temperature and volume O Will be higher than 0.457atm O Will be lower than 0.457atm

A mass of 2.74 g of an unknown gas is introduced into an evacuated 2.50 L flask. If the pressure in the flask is 0.80 atm at 120oC, which of the following gases might be in the flask? (R=0.0821 L* atm/mol* k) A. C4H10 B. C3H8 C. CH4 D. C2H2 E. C2H6
