Answer:
Oxygen 35.6 percent
Carbon 60 percent
Hydrogen 4.4 percent
Explanation:
Molecular mass of aspirin[tex](C_9H_8O_4)=180 gm/mol.[/tex]
Mass of carbon in 180 gm of aspirine[tex]=12\times 9=108\ gm.[/tex]
Therefore, percentage of carbon in aspirin is [tex]=\dfrac{108}{180}\times 100=60\ percent.[/tex]
Similarly, mass of hydrogen in 8 gm of aspirine[tex]=1\times 8=8\ gm[/tex].
Hydrogen's percentage in aspirin[tex]=\dfrac{8}{180}\times 100=4.4\ percent.[/tex]
Also, mass of oxygen in aspirin is [tex]=16\times 4=64\ gm.[/tex]
Oxygen's percentage in aspirin[tex]=\dfrac{64}{180}\times 100=35.6\ percent.[/tex]
Hence, this is the required solution.
