Homework Statement


This the calculation of AMU. I don't understand the calculation. The calculation is below:
¹²C₆ = 6.023 X 10²³
12 X 10⁻3 / Avogadro number = 1.99264654 X 10⁻²⁶
Why 12 X 10⁻3 it should be only 12 / Avogadro number
I am confused. Please simplify it.

The question is set out too confusedly to know what it is.
Please try again: give quotes if there is some text that is confusing you.
12/(6.023 X 10²³) g should be the mass of an atom of 12C.
I do not know what C6 is in this context.

As your instructor has undoubtedly told you millions of times, units are important.
