Respuesta :
1.24 moles of Mg(OH)2
In order to completely neutralize 2.48 mol of HNO3, 1.24 moles of Mg(OH)2 are needed.
The given chemical reaction is:
Mg(OH)₂ + 2HNO₃ → Mg(NO₃)₂ + 2H₂O
It is evident from the reaction's stoichiometry that:
2 moles of HNO₃ = reacts with 1 moles of Mg(OH)₂
2.48 moles of HNO₃ = reacts with (1/2)(2.48)=1.24 moles of Mg(OH)₂
Therefore, the required moles of Mg(OH)₂ is 1.24mol.
What does stoichiometry mean?
The reaction's stoichiometry provides information about the relative moles of reactants and products that are present in the specific chemical reaction.
How is stoichiometry determined?
In just four easy stages, nearly all stoichiometric difficulties can be resolved:
- Equilibrate the variables.
- Convert a given substance's units to moles.
- Calculate the number of moles of substance produced by the reaction using the mole ratio.
- Convert desired material moles to desired unit conversions.
Why is stoichiometry important?
- Calculating quantities in chemical equations is known as stoichiometry.
- Stoichiometry explains how much of each reactant is required in a chemical reaction to produce the appropriate amount of the end product.
