Question

How many moles in 2.24 L of a sample of gas.1 mol10 mole0.1 mole5 mol

Answer 1

`0.1\text{ mole}`

Step-by-step 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:

`\begin{gathered} x*22.4\text{ = 1}*2.24 \\ x\text{ = }(2.24)/(22.4) \\ \\ x\text{ = 0.1 mole} \end{gathered}`
