Divide 4.2x1024 by 6.022x1023 to get the number of moles.
The second number is Avogadro's constant, it represents the number of atoms in one mole of any substance.
So if you have X number of atoms given, and you are asked to find how many moles that is equal to just divide by Avagadro's constant to get the answer.
For this: it is 6.974 if you forget about sigdigs.
Rounded to the real number of sgnificant digits the answer is 7.0 mol of N-atoms or 3.5 mol of N2molecules.

How many neutrons does the nucleus of a nitrogen atom contain?
there are 7 neutrons because when you take away the number of protons, which is 7 as well, from the atomic mass, which is 14 when rounded, you get 7 which is the number of neutrons in nitrogen.
What subatomic particles are in a nitrogen atom?
there are 7 protons, 7 neutrons and 7 electrons
What is the mass number of an atom of nitrogen?
Nitrogen is a non metal element. Mass number of it is 14.
How many protons neutrons and electrons are in a nitrogen 15?
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
What is the charge of nitrogen-15?
There is no charge. Nitrogen-15 is an isotope, which refers to the number of neutrons. Neutrons do not have a charge.
How many neutrons does the nucleus of a nitrogen atom contain?
there are 7 neutrons because when you take away the number of protons, which is 7 as well, from the atomic mass, which is 14 when rounded, you get 7 which is the number of neutrons in nitrogen.
What subatomic particles are in a nitrogen atom?

N atom has 7 protons and a mass number of 14 What is the number of neutrons in an atom of N?
The mass number of an atom is the sum of its protons and neutrons. In this case, nitrogen (N) has 7 protons and a mass number of 14. So, the number of neutrons in an atom of nitrogen is 14 - 7 = 7 neutrons.
How many neutrons does an atom of nitrogen have if the mass number is 13?
6 neutrons
What is the mass number of an atom of nitrogen?
Nitrogen is a non metal element. Mass number of it is 14.
What determins the mass number of nitrogen?
The mass number of a nitrogen atom is determined by the mass of the nucleus. As it is the relative mass, it is equal to the combined number of protons and neutrons in the nucleus of the atom. For example, the most common isotope of nitrogen contains seven protons and seven neutrons, giving it a mass number of 14. Some atoms of nitrogen have an extra neutron, which gives a mass number of 15.
How many protons electron and neutrons are in nitrogen?
A neutral nitrogen atom has 7 protons, 7 neutrons, and 7 electrons. If it is electrically charged, the number of electrons will be different. If it is an isotope of nitrogen other than the most common (N-14), the number of neutrons will be different. Protons = Atomic Number Neutrons = Atomic Mass - Protons Electrons = Protons Atomic number is the amount of protons in element.
How many protons neutrons and electrons are in a nitrogen 15?
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
What is the atomic number for nitrogen-15?
The atomic number for nitrogen is 7, which means the nucleus of a nitrogen atom contains 7 protons. Since nitrogen-15 is a specific isotope of nitrogen, it still has 7 protons but also has 8 neutrons in its nucleus.
What is the charge of nitrogen-15?
There is no charge. Nitrogen-15 is an isotope, which refers to the number of neutrons. Neutrons do not have a charge.
If a silicon atom contains 16 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.
How many neutrons can be found in an atom of nitrogen?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element For the most important natural stable isotope of nitrogen - 14N - the number of neutrons is 7.
