Question

$22\mathrm{g}$ : $22\mathrm{g}$ of Carbon dioxide?

Answer 1

Mole:

• A mole is known as the amount of a substance that contains $6.02214076\times {10}^{23}$ entities of the given substance.
• Also, the mole of a substance is termed the mass of a substance containing the same number of fundamental units as there are atoms in exactly $12.000\mathrm{g}\mathrm{of}12\mathrm{C}.$

Step 1: Given data:

Mass of Carbon dioxide is given as =$20\mathrm{g}$

Also we know that the molar mass of Carbon dioxide =$44\mathrm{g}$

Step 2: Number of moles calculation formula:

The number of moles of any substance can be given as:

$\mathrm{No}\mathrm{of}\mathrm{moles}=\frac{\mathrm{given}\mathrm{mass}}{\mathrm{molar}\mathrm{mass}}$

Step 2:Calculating the number of moles in $22\mathrm{g}$ of Carbon dioxide :

The number of moles in $22\mathrm{g}$ of Carbon dioxide can be calculated as:

$$\begin{gathered} \mathrm{No}\mathrm{of}\mathrm{moles}=\frac{22\mathrm{g}}{44\mathrm{g}} \\ =0.5\mathrm{mole} \end{gathered}$$

Hence,$22\mathrm{g}$ of Carbon dioxide can be converted into $0.5\mathrm{mole}.$
