It is a salt and salt salt and
C=λν ==> λ=c/ν
λ= 3x10^8 m/s / 1.50 x 10^15 s^-1
λ= 2 x 10^-7 m
λ= 200 nm
The average atomic mass of chromium to 3 decimal points is 52. 055 g. mol.
<h3>What is the average atomic mass?</h3>
"The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass, also known as atomic weight."
Given the different isotopes of chromium.
The four isotopes of chromium are cr-50, cr-52, cr-53 cr-54.
The average atomic mass will be
Let us take the weighted average of your isotopes:
50 × 0.0434 + 52 × 0.8379 + 53 × 0.095 + 54 × 0.0237 = 52. 055 g.
Thus, the average atomic mass of chromium is 52. 055 g.
