Calculate the number of carbon atoms present in $11$ g of carbon dioxide.

Options:

Answer:

Solution:

Molar mass of $C O_{2} = 12 + 2 \times 16 = 44$ g/mol.

Number of moles of $C O_{2} = \frac{11}{44} = 0.25$ mol.

Each molecule of $C O_{2}$ contains one carbon atom.

Number of carbon atoms = $0.25 \times N_{A} = 0.25 \times 6.022 \times 1 0^{23} = 1.5055 \times 1 0^{23}$ .

Answer: $1.5055 \times 1 0^{23}$
