How many chlorine atoms are there in 16.0 g of carbon tetrachloride (CCl₄)?

Question

Quizplus · Accepted Answer

To find the number of chlorine atoms, we need to use the molar mass of carbon tetrachloride (CCl4), which is 154 g/mol.

Number of moles of CCl4 = 16.0 g / 154 g/mol ≈ 0.104 moles

Since there is 1 carbon atom and 4 chlorine atoms in each molecule of CCl4, we can find the number of chlorine atoms by multiplying the number of moles by 4.

Number of chlorine atoms = 0.104 moles × 4 = 0.416 ≈ 2.51 × 10^23

Therefore, the best choice is D) 2.51.
