Hi.
You can calculate mass percent by dividing the mass by the total mass of the compound & multiplying by 100.
28.8 ÷ (171.2 + 28.8) = 0.144
0.144 · 100 = 14.4
I believe the mass percent of the hydrogen in the compound is 14.4%

A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).E - 3. Organic carbon is converted to fossil fuels.H - 4. Carbon dioxide is converted to carbonates.F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).

Answer:
Explanation:
Since no information was provided about the can of soda, let's take an example of 1 can of 12 fl oz (368 g) Coca-Cola.
The nutrition facts state that it contains 33 g of sugar. In order to calculate the number of molecules, we firstly need to know the molecular formula of sugar. Sugar can be represented by 
.
Our first step is to find the molar mass of sugar:
Secondly, dividing mass of sugar, 
, by the molar mass will yield the number of moles of sugar:
Finally, multiplying moles by the Avogadro's constant will yield the number of molecules:
