QUESTION:

How many chlorine atoms are in each set?

(a) three carbon tetrachloride molecules

(b) two calcium chloride formula units

(c) four phosphorus trichloride molecules

(d) seven sodium chloride formula units

Step 1 of 4

Here, we are going to calculate the number of Chlorine atoms present in each  set.

Atom is the smallest tiny representation of an atom.

Chemical formula is the representation of the number of atoms present in the molecule or molecular compound .

(a) three carbon tetrachloride molecules

The molecular formula of carbon tetrachloride is $$\mathrm{CCl}_{4}$$

Thus total number of each atom in the molecule is $$=3 \times\left(C^{2} l_{4}\right)=C_{3} C l_{12}$$

Therefore, three carbon tetrachloride has = 12 chlorine atoms.
