Answer:
The formula would be: C₆H₈O
Explanation:
The mass of carbon dioxide formed = 627.4 mg
The percentage of carbon in the sample would be:
% carbon =
Where
44 is the molar mass of carbon dioxide.
The percentage of hydrogen in the sample would be:
% Hydrogen =
Rest will be oxygen = 100 -[74.92+8.33]=16.75
Let us calculate the moles of each of the elements present:
moles of carbon =
moles of hydrogen =
moles of oxygen =
The mole ration of carbon, hydrogen and oxygen = C:H:O = 6 : 8 : 1
so the formula would be:
C₆H₈O
The ability of a liquid to flow up a narrow tube which is unassisted against the gravity of the attraction between molecules of the same substance. The curvature which is of the surface of a liquid at the interface with the container, the attraction between dissimilar molecules for the resistance of a liquid to flow the elasticity of surface layer of liquid because of the liquid trying to minimize its surface area.
So what’s the question? I’m confused
