Question

what is the R.A.M of chlorine

Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$Calculating relative atomic mass from isotopic abundance

For example, chlorine has two isotopes: 35Cl and 37Cl. But the relative atomic mass of chlorine is not 36. In any sample of chlorine, 75 per cent of the atoms are 35Cl and the remaining 25 per cent are 37Cl.
