Answer:
The mass of an atom is found in its nucleus.
Explanation:
An atom is made of three different particles: protons, neutrons and electrons.
Protons (positive charge) and neutrons (no charge) each have a mass of 1 AMU. They are both found in the nucleus (centre) of the atom.
Electrons (negative charge) are considered to have a mass of 0. Their mass is not actually 0, but very close so we do not count them. They are not in the nucleus, but found in shells surrounding the atom.
To calculate the mass of an atom, we add the number of protons and the number of electrons.
m = P + N

An area or ridge of land that separates waters flowing to different rivers, basins, or seas.
Explanation:
Answer:
35.7%
Explanation:
The percent yield is calculated by the formula:
<em>[(actual yield) / (theoretical yield)] * 100</em>
In this case, the actual yield is 0.15 grams, and the theoretical yield is 0.42 grams. So, putting these values into the equation, we have:
Thus, the percent yield of 
is 35.7%.
Hope this helps!
