Final answer:
The volume of 2.75 moles of neon at STP is 61.6 liters.
Step-by-step explanation:
To determine the volume of 2.75 moles of neon at STP, we can use Avogadro's Law, which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. At STP, the molar volume of a gas is 22.4 liters. So, the volume of 2.75 moles of neon would be 2.75 * 22.4 = 61.6 liters.
