<h2>Hello!</h2>
The answer is: -97.37° C
<h2>Why?</h2>
According to the Charles and Gay-Lussac's Law we have that:

Where:
<em>v</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
From the Gay-Lussac's Law we also have the following relation:

Since we need to find the new temperature (T2) we can use the last equation:

We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:

So, the temperature is -97.37° C
Have a nice day!
Answer:
I am pretty sure that it is A. H2.
Explanation:
Sorry if it's wrong.
In 0.190 mole of C6H14O, there is 0.190*6 (number of C in one molecule) = 1.140 mole of C atoms. The total number of C atoms = 1.14 * 6*

(atoms of C in one mole) = 6.84*

atoms.
