| Oct 9, 2020 at 13:01 | comment | added | ProfRob | @ypercubeᵀᴹ a typical star contains 0.3*0.01 solar masses of heavy elements. A high mass star releases 3 solar masses of heavy elements. The number of typical stars that can thus be enriched is 3/(0.3*0.01) = 1000. | |

Where does the 1000 come from? 15 / 0.3 = 50, not 1000.
