Question

How many molecules of the sweetener saccharin can be prepared from 30 C atoms, 25 H atoms, 12 O atoms, 8 S atoms, and 14 N atoms?

 

Step-by-Step Solution

Answer

4 molecules of the sweetener saccharin can be prepared from 30 C atoms, 25 H atoms, 12 O atoms, 8 S atoms, and 14 N atoms

Given data

From the figure it can be identified one Saccharine molecule contains 7 carbon atoms, one nitrogen atom, five hydrogen atoms, three oxygen atoms, one sulfur atom. 

Determine number of molecules of saccharine

There is total 30 carbon atoms then as each molecule of saccharine contains 7 carbon atoms. So only four molecules of saccharine possible. 

 

There is total 25 hydrogen atoms Also, each molecule of saccharine contains five hydrogen atoms then four molecules contain 20 hydrogen atoms. So, four molecules of saccharine possible. 

 

 

There is total 12 oxygen atoms Also, each molecule of saccharine contains three oxygen atoms then four molecules contain 12 oxygen atoms. So only four molecules of saccharine possible. 

 

There is a total of 14 nitrogen atom. Each molecule of saccharine contains one nitrogen atoms then four molecules contain 4 nitrogen atoms. So, four molecules of saccharine possible.
