Question

calculation of atomic mass of nitrogen( no direct answer i want calculation)

​

Answer 1

Explanation:

Nitrogen is element number 7. Using this periodic table, we see the atomic mass of nitrogen is 14.01 amu or 14.01 g/mol. 2. Add up the number of neutrons and protons in a single atom.

Answer 2

Explanation:

now , 14x + (100-x)/100 = 14.0067

or -x = 1400.67-1500 = -99.33

or x = 99.33

thus % abundance of N 14 isotope = 99.33%

% abundance of N 15 isotope = 0.67%
