According to the claim, the carbon isotope that is 10% of something like the carbon 13.3 molecule has a mass number of 15.1.
Where can you find carbon?The majority of carbon is kept in reservoirs, or sources, such rocks and sediments; the remaining portion is kept in the atmosphere, the seas, and living things. Through the respiration of both and animals, carbon is returned to the atmosphere. Burning things like wood, oil, and gas also releases it.
Briefing:Since all carbon isotopes have an equal atomic mass of 13.3,
(0.60 * 13.3) + (0.3 * 12.7) + (0.1 * x) = 13.3
11.79 + 0.1x = 13.3
x = 15.1

Calculate the percent composition of H3PO4
The percent composition of hydrogen, phosphorous and oxygen in phosphoric acid is 3.06 %,31.60%,65.31 % respectively.
What is percent composition?Percent composition is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.There are two types of percentage composition percent weight by volume and percent volume by volume .
Percent composition of hydrogen=3/97.99×100=3.06%.
Percent composition of phosphorous=30.97/97.99×100=31.60%
Percent composition of oxygen=64/97.99×100=65.31%
