A 8.5-liter sample of a gas has 1.2 mole of the gas. If 0.65 mole of the gas is added, what is the final volume of the gas? Temperature and pressure remain constant.

Explanation:

0.7347 moles

How many moles of gas are in a sample of gas at a pressure of 1.2 atm, a volume of 21 liters, and a temperature of 145 ⁰C? (Hint: K = ⁰C + 273) There are 0.7347 moles of gas in the sample.
