You need to first find the limiting reagent/element in the formula. Solve for moles for each.
10.0g of Hg*(1 mole of Hg/200.6g of Hg)= moles of Hg
10.0g of Br2*(1 mole of Br2/159.8g of Br)= moles of Br
Looking at it Br2 will be your limiting element/reagent
moles of Br2/360.41 g of HgBr2/mol= g of HgBr2
Hg was the limiting reagent, not Br2.
moles of Hg/360.41 g of HgBr2/mol= g of HgBr2
