confirm that the average atomic weight of Cr is
A) 50.941 amu
B) 51.996 amu
C) 52.940 amu
D) 53.939 amu
The average atomic weight of chromium (Cr) is approximately 51.996 amu.
This value reflects the weighted average of the isotopes of chromium that occur naturally, taking into account their relative abundance. Chromium has several isotopes, but the most stable and abundant one contributes most significantly to this average.
So, the correct answer is B) 51.996 amu.
