Final answer:
To determine the number of moles of neon at STP, we can use the molar volume of a gas at STP, which is 22.4 L/mol. Setting up a proportion, we find that there are 2 moles of neon in 44.8 liters at STP.
Step-by-step explanation:
To determine the number of moles of neon present in 44.8 liters of neon at Standard Temperature and Pressure (STP), we can use the molar volume of a gas at STP, which is 22.4 L/mol. So, we can set up a proportion:
22.4 L = 1 mol
44.8 L = x mol
Cross-multiplying, we get:
22.4x = 44.8
x = 44.8 / 22.4
x = 2 moles
Therefore, there are 2 moles of neon present in 44.8 liters of neon at STP.
