First, set up a proportion:
You have 2.00 g Carbon and 7.33 g of the total substance (find it by adding 2.00g C + 5.33 g O)
You have an unknown g carbon with 55.0 g o total substance.

So:
$\frac{2.00}{7.33} = \frac{x}{55.0}$

Multiply 2.00 by 55.0 and divide the answer by 7.33
You'll get 20.63...

Why don’t all of the particles in an atom contribute to the mass?

kotegsom [21]

Answer:

Explanation:

The mass of an atom is dependent on its number of protons and neutrons. Electrons have mass, but are too light in comparison to protons and neutrons to contribute towards the overall mass. Their relative mass is about 1/1840 compared to 1 for protons and neutrons, and therefore are not counted in the mass.

Hope this helped!
