Chemistry HELP ASAP!!!?
You have two samples of the SAME organic compound one weighing 8.28 g and the other weighing 15.07 g. Would the mass of EACH element in the sample weighing 15.07 be the same as, less than, or more than the mass of the 8.28 g organic compound?
Please explain answer. Thank you.

The same
The weight of atoms/elements is always the same (check your periodic table)
Example: Element =Carbondioxid (CO2)
CO2 weighs (12+2*16) 44u (units) no matter how many you have

Lets pretend your sample is water [two hydrogen atoms for every one oxygen atom].
If you double the mass of water, you double the number of hydrogen and oxygen atoms (their ratio stays the same). Make sure you re-read the question carefully, because increasing the mass will increase the number of atoms but will not change there ratio. As your question is written here the answer is the 15 gram sample contains more atoms than the 8 gram sample.
