Final answer:
To find the volume of 4.21 moles of neon gas, we can use the concept of molar volume at STP. The volume would be 94.184 liters.
Step-by-step explanation:
The question is related to the subject of Chemistry, specifically to the topic of gases. The student is asking about a container that holds 4.21 moles of neon gas. To find the volume of the gas, we can use the concept of molar volume, which is the volume occupied by one mole of a gas at standard temperature and pressure.
Using the molar volume of gases at STP, which is 22.4 liters/mol, we can calculate the volume of the 4.21 moles of neon gas.
Volume = Moles x Molar Volume = 4.21 mol x 22.4 L/mol = 94.184 liters.
