Understanding the Concepts
* STP (Standard Temperature and Pressure): STP is defined as 0°C (273.15 K) and 1 atm (101.325 kPa) pressure.
* Molar Volume: At STP, one mole of any ideal gas occupies a volume of 22.4 liters.
Calculation
1. Use the Molar Volume: Since 1 mole of any gas occupies 22.4 L at STP, we can set up a proportion:
1 mole / 22.4 L = 0.75 moles / x L
2. Solve for x (the unknown volume):
x = (0.75 moles * 22.4 L) / 1 mole
x = 16.8 L
Answer: The volume of 0.75 moles of carbon dioxide gas at STP is 16.8 liters.
