Equal Masses Between Two Atoms

Postby Noh_Jasmine_1J » Sat Sep 29, 2018 7:51 pm

Referring to question E.3, how do you know to increase astatine atoms by 3? It gives you 9 gallium atoms (molar mass 70 g/mol) and 9 astatine atoms (molar mass 210 g/mol) and asks how many astatine atoms are needed to make the masses equal.

Update: I realized that the astatine atoms weren't on the pan and figured it out!
