The correct answer is: [C]:

"<span>pressure and the number of gas molecules are directly related."
___________________________________________________________
<u>Note</u>: The conclusion was: "</span> as the pressure in a system increases, the number of gas molecules increases" — over the course of many trials.
This means that the "pressure" and the "number of gas molecules" are directly related.
Furthermore, this conclusion is consistent with the "ideal gas law" equation:
" PV = nRT " ;
____________________________________________________________
in which:
"P = Pressure" ;
"n = number of gas molecules" ;
___________________________________________________________
All other factors held equal, when "n" (the "number of gas molecules")
increases in value (on the "right-hand side" of the equation), the value for "P" (the "pressure" — on the "left-hand side" of the equation), increases.

The ratio of carbon and hydrogen must be the same.
Answer:
Robert
Explanation:
There is not more than one colour
You can use M x V = M' x V'
3 x V = 250 x 1.2
V = 100 ml
