Mass of  Magnesium bromide : 5.76 g

<h3>Further explanation</h3>

Complete question

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

<em />

Reaction

<em />\tt Mg+Br_2\rightarrow MgBr_2<em />

mol Mg

\tt \dfrac{1}{24}=0.042

mol Br₂

\tt \dfrac{5}{160}=0.0313

Limiting reactants : Br₂(smaller)

mol MgBr₂ = mol Br₂=0.0313

mass MgBr₂ :

\tt 0.0313\times 184,113 =5.76~g
