Question

At STP what is the volume of 1.0 mole of carbon dioxide?

a)1.0 L
b)44.0 L
c)273 L
d)22.4 L
e)12.2 L

Answer 1

At STP, 1.0 mole of carbon dioxide or any ideal gas occupies a volume of 22.4 L. The correct option is d.

Step-by-step explanation:

At Standard Temperature and Pressure (STP), which is defined as 0°C (273 K) and 1 atm pressure, the volume of 1.0 mole of any ideal gas, including carbon dioxide, is 22.4 L. This value is known as the standard molar volume of a gas. It serves as a very useful conversion factor in stoichiometry problems when the conditions are at STP. Therefore, the correct answer to the question is d) 22.4 L.
