By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
The atomic weight is14.00674
The atomic mass number of nitrogen is 14.0
To find the proportion of N in Ca3N2, we calculate the total atomic mass of N in the compound which is 2 * 14 = 28 (since there are 2 nitrogen atoms in Ca3N2). The total atomic mass of Ca3N2 is 3 * 40 + 2 * 14 = 136. Therefore, the proportion of N in Ca3N2 by mass is 28/136 = 0.206 (or 20.6%).

The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
The formula mass of nitrogen monoxide (NO) is calculated by adding the atomic masses of nitrogen (N) and oxygen (O). The atomic mass of nitrogen is approximately 14 atomic mass units (amu) and the atomic mass of oxygen is approximately 16 amu. Therefore, the formula mass of NO is 14 + 16 = 30 amu.
Z is atomic number A is atomic mass N is number of neutrons Z=A-N 79 = 179 - N 179-79=100 so number of neutrons is equal to 100 This is one thing you can get from that given.
For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.
The atomic mass of NH4Cl can be calculated by adding the atomic masses of each element in the compound. The atomic masses of nitrogen (N) is 14.01, hydrogen (H) is 1.01, and chlorine (Cl) is 35.45. By adding these values together, the atomic mass of NH4Cl is 53.46 g/mol.
