Step 4: Find the percent abundance To get percent abundance, we will multiply the relative abundance value by 100 and put a percent (%) sign. As we have now x= 0.76. Simply, multiply by 100 to get percent. So, chlorine-35 is 0.76*100=76% Now, For chlorine-37, we get (1-x) = (1-0.76) = 0.24 Multiplying above by 100, we get 24%. 2022. 5. 30. · Solution: 1) First question: If chromium has four isotopes, they have to add up for a sum of 100%, so the abundance of the third one is 9.765%. A change in the number of neutrons.

Every element has different isotopes that occur naturally on Earth. Some isotopes are more abundant than others. The percent abundance's are shown for each elements isotope and the weighted average will be closer to the MOST ABUNDANT isotope. Average atomic mass: a weighted average that uses the percent abundance and mass of all naturally.
Isotope Z50 Z52 Z53 Z54 Relative abundance 4.34 83.79 9.50 2.37 (a) Using the axis below, sketch the expected mass spectrum that these data would provide. Label the axes and pay attention to the size of any lines that you draw. (4) (b) Calculate the average atomic mass of Z and identify the element. (3).
