1 mol Cu - 2 mol Ag
x - 0.854 mol Ag
x=0.854*1/2=0.427
0.427 mol Cu
Answer:
22g
Explanation:
Given parameters:
Mass of element A = 18g
Mass of element B = 4g
Unknown:
Mass of compound formed = ?
Solution:
The reaction equation is given as;
A + B → AB
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".
Simply mas is conserved and the mass of the reactants is the same as the mass of the product that forms.
Mass of reactants = mass of A + mass of B = 18g + 4g = 22g
So;
Mass of product AB = 22g
