What is the average atomic mass (in amu) for element A?

somy · Answer

multiply each mass by its percentage and then add them all up 
(31.6800 * 83.04) + (32.6700 * 0.5000) + (33.6600 * 0.07000) + (36.6300  * 16.39) = and get the answer 

then divide what you get by 100 
so this will be your final answer
