Question

Asprin is a compond with the molecular formula, C9H8O4. What is the percent composition?

Answer 1

Oxygen 35.6 percent

Carbon 60 percent

Hydrogen 4.4 percent

Step-by-step explanation:

Molecular mass of aspirin
`(C_9H_8O_4)=180 gm/mol.`

Mass of carbon in 180 gm of aspirine
`=12* 9=108\ gm.`

Therefore, percentage of carbon in aspirin is
`=(108)/(180)* 100=60\ percent.`

Similarly, mass of hydrogen in 8 gm of aspirine
`=1* 8=8\ gm`.

Hydrogen's percentage in aspirin
`=(8)/(180)* 100=4.4\ percent.`

Also, mass of oxygen in aspirin is
`=16* 4=64\ gm.`

Oxygen's percentage in aspirin
`=(64)/(180)* 100=35.6\ percent.`

Hence, this is the required solution.
