@Astrophysics  Can you help me plz?

astrophysics · Answer

Ooh I remember doing this back in the day..let me see now

astrophysics · Answer

Ok so we have C = 98.28g, H = 16.21 g, and O = 65.2 g right

anonymous · Answer

Yes @Astrophysics

astrophysics · Answer

Ok so what is the total number of grams?

anonymous · Answer

Do i suppose to add them together? @Astrophysics

astrophysics · Answer

Yes, add it all together what do you get?

anonymous · Answer

179.69 @Astrophysics

astrophysics · Answer

Good, now simply take the number of grams from carbon and divide it by the total amount which will give you a ratio of the amount of carbon in the compound

astrophysics · Answer

Then multiply by 100 for the percent :) make sense?

astrophysics · Answer

$$\frac{ Carbon }{ Total  } \times 100$$

anonymous · Answer

98.28g divide by 179.69g= 0.546 ....Right?

astrophysics · Answer

Good! Now multiply by 100 for the percent :)

anonymous · Answer

0.546 x 100=54.6

astrophysics · Answer

:)
