Question

A sample of hydrogen gas at 300 K and 0.185 atm occupies a volume of 2.60 L. If the pressure of the gas is increased, while at the same time it is heated to a higher temperature, the final gas volume

A) will be larger than 2.60 L.

B) could be larger or smaller than 2.60 L depending on the final pressure and temperature.

C)will be smaller than 2.60 L.

Which of the following gas samples would have the largest volume, if all samples are at the same temperature and pressure?

A) 79.9 grams of Ar

B) 5×10²³ molecules of O₂

C) 4.01 moles CH₄

D) they would all have the same volume

A sample of neon gas collected at a pressure of 0.947 atm and a temperature of 281 K is found to occupy a volume of 541 milliliters. How many moles of Ne gas are in the sample? _____mol
