Is it not 87.0*g*mol^-1?

Explanation:

This site tells me that ""^87Sr is approx. 7.00% abundant. The molar mass quoted on the Periodic Table is 87.62*g*mol^-1. As always this molar mass is the weighted average of the individual isotopic masses. ""^88Sr, at approx. 83% abundance, is the major isotope.
