The average mass of a boron atom is 10.81. You perform an experiment using mass spectrometry and find 90% of the boron atoms have a mass of 11 a.m.u., 6% have a mass of 10 a.m.u. and 4% have a mass of 12 a.m.u. What is the experimental mass for boron based on YOUR measurements? O 11 amu O 10.81 amu O 10 amu O 12 amu O 10.98 amu
