Homework Statement

its asking me if if it is easier to use the mass units

Homework Equations

PART A

The Attempt at a Solution

its it easier to to use numbers given becuz

when add the numbers

(3.9) / ( 1 - 16 / (16+133) ) = 4.3 = kinetic energy needed for O ionize C
4.3 > 4 therefore, O will not ionize

right?

the answer is YES

Careful. The question is "Is it possible to ionize...". They are not asking about units, they are telling you that certain units are easier to use.
