If the specific gravity of acetic acid is 1.040 at 30.0 °C, what is the density of acetic acid at 30.0 °C?

Hello!

In this equation, the element we are working with is C, which is carbon. The number 6 represents the atomic number, and 13 is the atomic mass.

We know that the number of elections are equal to the atomic number, and the number of protons are also equal to the atomic number.

While, the number of neutrons are determined by subtracting the atomic mass by the atomic number.

13 - 6 = 7 neutrons

Therefore, there are 6 protons, 6 electrons, and 7 neutrons.
