B., the mass of the nucleus of the atom.
Both the protons and the neutrons are inside the nucleus. The atomic number of an atom is the number of protons, and if you subtract the atomic number from the atomic mass you can find the number of neutrons an atom has.
So, the mass of the protons plus the mass of the neutrons, which are both inside the nucleus, equals the atomic mass.
Answer:
The identity of an atom is determined my the number of <u>protons</u>. This is the <u>atomic number</u>.
The particle(s) found inside the nucleus are called <u>protons and neutrons</u>. Their combined mass is referred to as <u>the mass number</u>.
Isotopes have the same number of <u>protons</u>, but different number of <u>neutrons</u>.
Options for given question are as follow,
<span>It has the largest volume.
It has the most solute for a given volume.
It has the greatest amount of solute.
It has the most volume for a given amount of solute.
Answer:
Option B (</span>It has the most solute for a given volume) is the correct answer.
Explanation:
Concentration of solution is the amount of solute dissolved per volume. Amount of solute and concentration are directly related when volume is kept constant while, volume and concentration are inversely related when amount of solute is kept constant.
In option-B it is clearly given that the volume is kept constant and the amount of solute is being increased. Hence, it is the best choice.
