Answer:
[tex]0.1\text{ mole}[/tex]Explanation:
Here, we want to get the number of moles in 2.24 L of a sample of gas
Mathematically,
At STP, 1 mole of a gas occupies a volume of 22.4 L
Thus x moles will occupy 2.24 L at STP
To get the value of x, we have it that:
[tex]\begin{gathered} x\times22.4\text{ = 1}\times2.24 \\ x\text{ = }\frac{2.24}{22.4} \\ \\ x\text{ = 0.1 mole} \end{gathered}[/tex]
