In a separate experiment, 5.6 grams of the vaporized compound was found to occupy 1.09 liters at 226°C and 785 mmHg. Determine the molar mass and molecular formula of the compound.

A sample of a gas with an empirical formula of Ch2 weighs 4.48 grams and occupies a volume of 2.15 Lat 328K and 1.00 atm. What is the molecular formula of the gas?

A sample of neon at 25°C occupies a volume of 500. L at 2.00 atm. How many moles of neon are present? Provide an answer correct to 2 significant figures. Do not use scientific notation. Do not include units in your answer. For example, if you calculate that the correct answer is 514 cm3, simply type "510" in the box without the quotation marks (") or units as part of your answer.

A scientist isolates a sample of gas that occupies a volume of 976.7 mL at 98.1 kPa and 19.47 degrees Celsius. If the gas has a molar mass of 64.0 5 g/mol. Calculate the mass of the sample in grams. Provide your answer to TWO decimals.
