The answer would be B. 17 g because nitrogen's approximate mass is 14, adding to that 3 because of the three hydrogen's adds up to 17.
Molar mass :
CO₂ = 44.0 g/mol
CH₄ = 16.0 g/mol
The balanced equation is wrong ,<span>this is the correct :</span>
<span>CH</span>₄<span> + 3 O</span>₂<span> = CO</span>₂<span> + 2 H</span>₂<span>O</span>₂<span>
</span>
16.0 g -------------> 44 g
184.5 g -----------> mass of methane
mass of methane = 184.5 x 44 / 16.0
mass of methane = 8118 / 16.0
mass of methane = 507.375
moles of Carbon dioxide ( CO₂)
507.375 / 44.0 => 11.531 moles of CO₂
hope this helps!
The most appropriate answer is 'acetic acid contains a significant amount of carbon, but sodium hydroxide contains no carbon'. Organic compounds are those compounds that contains carbon atoms usually bonded to other elements such as oxygen, nitrogen and hydrogen. Organic compounds contain covalent single, double or even triple bonds.
