There are 11 Carbon atoms in the compound.
<u>Solution:</u>
Carbon atom count is the ratio of the M peak to the M+1 peak.

Here M peak is 57.10% and M+1 peak is 6.83%. On applying the values in the formula we get,

Therefore, the number of Carbon atoms in the compound are 11.
Refer the image attached below for a better understanding of M peak and M+1 peak.
The heaviest ion that has the greatest m/z value is said to be the molecular ion peak in mass spectrum.
Temperature decreases (?)
Answer:
128g
Explanation:
Given parameters:
Mass of carbon = 48g
Mass of carbon dioxide = 176g
Unknown:
Mass of oxygen that reacted = ?
Solution:
Every chemical reaction must obey the law of conservation of mass. It states that "in a chemical reaction, matter is neither created nor destroyed" .
So;
Mass of carbon + Mass of oxygen = Mass of carbon dioxide
Mass of oxygen = Mass of carbon dioxide - Mass of carbon
Mass of oxygen = 176 - 48 = 128g
