Problem

A sample of chromium has the following isotopic composition by mass.

Isotope	$^{50}\text{Cr}$	$^{52}\text{Cr}$	$^{53}\text{Cr}$	$^{54}\text{Cr}$
Relative abundance / %	4.31	83.76	9.55	2.38

Calculate the relative atomic mass of chromium based on these data, giving your answer to two decimal places.
