Percent composition is the quantity or number of parts of a component contained in 100 parts of the total.
Given the the total is 100 g, the reported quantities for each component are the same percent.
Then, the percent composition of each as part of the entire sweet peas is:
Carb: 14.5%
Sugar: 5.7%
Diet. fiber: 5.1%
Prot: 5.4%
Fat: 0.4%
The rest to make the 100% is supposed to be water.
You could also find the percent composition in dry basis, which is done in this way (this is not what the question asks but it is good to know it).
Total components without water: 14.5 + 5.7 + 5.1 + 5.4 + 0.4 = 31.1 grams
Now divide each content by the total (31.1) and multiply by 100.
I will do one example:
Carbs: [14.5 / 31.1 ] * 100 = 46.6%
Compounds that have the same chemical formula but different arrangement of atoms are called ISOMERS. Isomer have the same molecular formula but different structural arrangements. There are different types of isomers: stereoisomers, constitutional isomers and enatiomers.
2.5 moles of NaCl as a single particle albeit, a fairly large particle, weighing in at about 146.1 grams
O2 isn't necessary for rusting, but some source of oxygen is required. Rust is just another name for iron oxide, and without oxygen there can't be oxide.

I'm almost certain its C. 3
I hope this helps and let me know if it's correct!
