of chlorine of isotopic number 1 (atomic weight = 35) and of 23.35 per cent. of isotopic number 3 (atomic weight = 37). It is of interest to determine the composition of this element in meteorites, and this has been done by the present writers, with the result that meteoritic chlorine...
We don't round it to a whole number because we want the number of the relative atomic mass of cholorine to be as precise as possible. We really care about the significant figures, so it's better if we get more digits.
