Problem 89P

How many chlorine atoms are in each set?

(a) three carbon tetrachloride molecules

(b) two calcium chloride formula units

(d) seven sodium chloride formula units

Step-by-Step Solution:

Step 1 of 3

Solution 89P

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 CCl4

Thus total number of each atom in the molecule is = 3 x (CCl4 ) = C3Cl 12

Therefore, three carbon tetrachloride has = 12 chlorine atoms.

(b) two calcium chloride formula units

Formula unit is the basic unit of ionic compounds. The formula unit of calcium chloride is CaCl2.

Thus total number of each atom in the molecule is = 2 x ( CaCl2 ) = Ca2Cl 4

Therefore, two calcium chloride has = 4 chlorine atoms.

The molecular formula of phosphorus trichloride is PCl3

Thus total number of each atom in the molecule is = 4 x (PCl3 ) = P4Cl 12

Therefore, four phosphorus trichloride has = 12 chlorine atoms.

(d) seven sodium chloride formula units

Formula unit is the basic unit of ionic compounds. The formula unit of sodium chloride is NaCl.

Thus total number of each atom in the molecule is = 7 x ( NaCl ) = Na7Cl 7

Therefore,seven sodium chloride has = 7 chlorine atoms.
