Question

How would you calculate the average atomic mass of element,X, if a sample of X is 22.50% x-37 and 77.50% x-35.?

Answer 1

Average atomic mass`=(0.2250xx37)+(0.7750xx35)=35.45`

Explanation:

Convert the percentages to decimals by dividing by 100. Then multiply each one by its corresponding mass and add the results.

Average atomic mass`=(0.2250xx37)+(0.7750xx35)=35.45`
