Mass of Magnesium bromide : 5.76 g

Complete question

What mass of Magnesium bromide is formed when 1.00 g of magnesium reacts with 5.00 g of bromine?

Reaction

$\tt Mg+Br_2\rightarrow MgBr_2$

mol Mg

$\tt (1)/(24)=0.042$

mol Br₂

$\tt (5)/(160)=0.0313$

Limiting reactants : Br₂(smaller)

mol MgBr₂ = mol Br₂=0.0313

mass MgBr₂ :

$\tt 0.0313* 184,113 =5.76~g$
