# Problem: At 4.00 L, an expandable vessel contains 0.864 mol of oxygen gas. How many liters of oxygen gas must be added at constant temperature and pressure if you need a total of 1.72 mol of oxygen gas in the vessel?Express the volume to three significant figures and include the appropriate units.Avogadro's law states that the volume of a gas at a given temperature and pressure is directly proportional to the number of moles of the gas.

🤓 Based on our data, we think this question is relevant for Professor Chibba & Davis' class at McMaster University.

###### Problem Details

At 4.00 L, an expandable vessel contains 0.864 mol of oxygen gas. How many liters of oxygen gas must be added at constant temperature and pressure if you need a total of 1.72 mol of oxygen gas in the vessel?

Express the volume to three significant figures and include the appropriate units.

Avogadro's law states that the volume of a gas at a given temperature and pressure is directly proportional to the number of moles of the gas.
