Q. 2.17 P - Chemistry: Molecular Nature Of Matter And Change

Question

Does the percent by mass of each element in a compound depend on the amount of that element used to make the compound? Explain.

 

Step-by-Step Solution

Answer

 

Yes, percent by mass of each element in a compound depends on the amount of that element used to make the compound.

Step 1: Mass percent of an element

Mass percent is calculated using the following formula: 

$Mass percent = \frac{Mass of the element in the compound}{Mass of the compound }\times 100$

       

Step 2: Mass of each element in a compound

From the formula we can say that higher the mass of the element, higher will be its mass percentage. Thus, percent by mass of each element in a compound depends on the amount of that element used to make the compound.
