Problem 66P

For each set of molecular models, write a relationship between moles of oxygen and moles of molecules. Then determine the total number of oxygen atoms present. (H— white; O—red; C—black; S—yellow)

(a) 

(b) 

(c) 

Step-by-Step Solution:
Step 1 of 3

Solution 66P

Here, we have to write a relationship between moles of oxygen and moles of molecules and determine the total number of oxygen atoms present. (H— white; O—red; C—black; S—yellow)

(a) 

The given compound is SO3(Sulfur trioxide)

Here, each molecule contains 1 Sulfur(S) atom and 3 oxygen(O) atoms.

So, the relationship between moles of oxygen and moles of molecules is :

        1 mol SO3 = 3 atoms of O.

There are total of 3 molecules of SO3.

 So, the total number of O atoms present in the given sample are :

= 3 3 atoms of oxygen(O) of each molecule = 9 oxygen(O) atoms

Hence,the total number of O atoms present in the given sample are 9.

(b) 

The given compound is H2SO4(Sulfuric acid)

Here, each molecule contains 2 hydrogen(H) atoms, 1 Sulfur(S) atom and 4...
