Mass of Magnesium nitrate produced : 593.2 g
Further explanation
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2HNO₃ + Mg(OH)₂ → Mg(NO₃)₂ + 2H₂0
mol HNO₃ = 8
From the equation, mol ratio of HNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :
[tex]\tt \dfrac{1}{2}\times 8=4~moles[/tex]
Mass Mg(NO₃)₂(MW=148,3 g/mol) :
[tex]\tt mass=mol\times MW\\\\mass=4\times 148,3 g/mol\\\\mass=593.2~g[/tex]
