Question

Using the isotopes of the element with16 protons, calculate the molar mass of that element?
24.0% of the atoms of the element has 16 protons and 13 neutrons
37.0% of the atoms of the element has 16 protons and 14 neutrons
23.0% of the atoms of the element has 16 protons and 17 neutrons
16.0% of the atoms of the element has 16 protons and 20 neutrons

Answer 2

The molar mass of the element can be calculated by taking the average as shown below

average atomic mass =0.24×29 + 0.37 ×30 + 0.23 × 33 + 0.16×36

                                   =6.96 + 11.1 + 7.59 + 5.76

                                    =31.41 amu
