Using the atomic masses and relative abundance of the isotopes of nitrogen given below, determine the average atomic mass of nitrogen.

N-14: 14.003 amu; 99.63%

N-15: 15.000 amu; 0.37%


A)14.003 amu


B)14.007 amu


C)14.506 amu


D)15.000 amu

Verified Answer :

amm= (%×mass1 +%×mass2)/100 just put the known values (99.63×14.003+0.37×15)/100 =14.007
