ella [17]

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 :

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