Question

Boron consists of two isotopes. The reported mass of boron is the weighted average of these two isotopes.

Part 1: Complete the equation below that shows how to calculate the actual mass of a boron atom using x for the abundance of B-11 and y for the abundance of B-10.

Part 2: If x and are the fractional abundances of each isotope, then what must x and y add up to?

x+y=?

Actual mass of B =
mass of 10B
mass ofB
X

Image Transcription

Actual mass of B = mass of 10B mass ofB X
