Answer:
mass of Cu = 26,34615g
Explanation:
The equation for reaction is
Cu + 2 AgNO3 ---> Cu(NO3)2 + 2 Ag
1mol 2mol 1mol 2mol
mass of Ag that reacted = 89.5g
molar mass of Ag =107.86h/mol
number of moles = mass/molar mass
number of moles of Ag = 89.5/107.86
=0.8298moles
from the stoichoimetric relation;
1mol of Cu reacted to produce 2moles of Ag;
hence 0.8298moles of Ag produce would require; 0.8298/2 moles of Cu to react
=0.4149moles of Cu
mass of Cu = moles of Cu * molar mass of Cu
molar mass(Cu) = 63.5g
mass of Cu = 0.4149 * 63.5
mass of Cu = 26,34615g
