Question

sample of oxygen gas (o₂) has a quantity of 2.0 moles at standard temperature and pressure (stp). what is the volume of this gas?
22.4 l
89.6 l
44.8 l
11.2 l
clear all

Explanation:

Step1: Recall STP molar volume

At STP (standard temperature and pressure), 1 mole of any ideal gas occupies a volume of \( 22.4 \, \text{L} \).

Step2: Calculate volume for 2.0 moles

Use the formula \( V = n \times V_m \), where \( n = 2.0 \, \text{mol} \) and \( V_m = 22.4 \, \text{L/mol} \).
\( V = 2.0 \, \text{mol} \times 22.4 \, \text{L/mol} = 44.8 \, \text{L} \)

Answer:

44.8 L (corresponding to the option with 44.8 L)
