Question

1. Use the concepts of relative abundance and relative weight to explain why carbon has an atomic mass of 12.011 amu when there are three isotopes of carbon weighing 12 amu, 13 amu and 14 amu. Why is the atomic mass not 13?

2. Explain the role of relative weight in determining the atomic mass of an element.

3. Differentiate between atomic number and mass number. Why is atomic number listed on the periodic table but mass number is not? 

4. An element has five isotopes. Calculate the atomic mass of this element using the information below. Show all your work. Using the periodic table, identify the element this is likely to be and explain your choice.

Isotope 1 – mass:  64 amu; percent abundance:  48.89%

Isotope 2 – mass:  66 amu; percent abundance:  27.81%

Isotope 3 – mass:  67 amu; percent abundance:  4.11%

Isotope 4 – mass:  68 amu; percent abundance:  18.57%

Isotope 5 – mass:  70 amu; percent abundance:  0.62%
