Question

What is the mass percent of carbon in tryptophan

Answer 1

Answer:64.7%

Step-by-step explanation:

The formula for tryptophan is
`C_(11)H_(12)N_(2)O_(2)`

Mass of
`C` in tryptophan is
`11* 12=132g`

Mass of
`H` in tryptophan is
`12* 1=12g`

Mass of
`N` in tryptophan is
`2* 14=28g`

Mass of
`O` in tryptophan is
`2* 16=32g`

So,
`\text{total mass}=132+12+28+32=204g`

`\text{mass of carbon}=132g`

`\text{mass percent of carbon}=\frac{\text{mass of carbon}}{\text{total mass}}* 100 =(132)/(204)* 100 =64.7`%
