Average Atomic Mass

Question 1

What do you need to know it order to find out the average atomic mass?

Answer 1

Isotope, mass, percent abundance, relative abundance, relative mass

Question 2

Relative abundance

Answer 2

isotope, mass, and percent abundance will be given but to convert percent abundance to relative abundance, move the decimal over two places

Question 3

Relative mass

Answer 3

after following steps to finding relative abundance, multiply relative abundance by mass to get relative mass (round if necessary)

Question 4

Final mass

Answer 4

add all of the relative mass going down the chart to get the final answer (round if necessary)
