How to find % Composition.
Find atomic mass of each element, divide atomic mass by atomic mass of all elements total, multiply by 100 to get percent.
Find atomic mass of each element, divide atomic mass by atomic mass of all elements total, multiply by 100 to get percent.
% Composition.
How to find average atomic mass
Make percents into decimals, multiply by numbers that are being averaged (# next to elements), add both values and divide by two to find average.
