ANSWER:
Solution 11Q
Step 1:
Given :
We can use mass percent composition as a conversion factor between grams of a constituent element and grams of the compound to write the conversion factor (including units) inherent in each mass percent composition.
Mass Percent composition is the percent by mass of each element present in a compound.
Mass percent composition = 100
