The mass formed in a chemical reaction is given by stoichiometry law in balanced chemical equation. The mass of silver produced in the reaction is 107. 9 g.
<h3>What is the stoichiometric law?</h3>The stoichiometric law states that in a balanced chemical equation, the stoichiometric coefficient describes the moles of each compound in a chemical reaction.
The balanced chemical equation for the reaction is:
From the balanced chemical equation, 1 moles of copper results in 2 moles of silver.
Moles in terms of mass can be given as:
Thus, moles of 31. 75 grams copper is:
The moles of Ag produced can be given from stoichiometric law as:
The moles of Ag produced is 1 mol.
The mass of a mole of element is equivalent to the molar mass. Thus, the mass of Ag produced in the reaction is 107. 9 g. Hence, option B is correct.
