Question

How many chlorine atoms are there in 100 g of carbon tetrachloride

Answer 1

Answer:

1.566x10²⁴ atoms of Cl

Explanation:

In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:

Moles CCl₄: 153.82g/mol

100g * (1mol / 153.82g) = 0.65 moles CCl₄

Moles Cl:

0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl

Atoms Cl:

2.6 moles Cl * (6.022x10²³ atoms / mol) =

1.566x10²⁴ atoms of Cl
