Question

Calculate the average atomic mass of Mg using the followinf data% Natural
Abudance.&. Molar mass
24Mg. 80. 24
25Mg. 10. 25
26Mg. 10. 25

​

Answer 1

Answer:

Change each percent abundance into decimal form by dividing by 100. Multiply this value by the atomic mass of that isotope. Add together for each isotope to get the average atomic mass.
