Question

Calculate the relative abundances of the isotopes of boron if Boron-10 has a mass of 10.0129 amu and Boron-11 has a mass of 11.0093 amu.

Accepted Answer

Boron-10 = 19.9%; Boron-11 = 80.1%

Answer

Boron-10 = 80.0%; Boron-11 = 20.0%

Answer

Boron-10 = 22.5%; Boron-11 = 77.5%

Answer

Boron-10 = 93.1%; Boron-11 = 6.84%
