Question

How many gram of silver iodide can be made from 4.45 grams of silver

Answer 1

STOICHIOMERTC EQUATION :

2 Ag + I₂    ------------> 2 AgI

I.e   2 mole of   Ag produces 2 moles of AgI

no of moles of Ag taken in rection = given mass / molar mass =   4.45g/108   = 0.0412 moles moles of Ag

so it should produce 0.0412 moles of   AgI,

mass produces =   no of moles X molar mass of AgI   = 0.0412 X 235    =    9.7 g of AgI produced.

so,   4.45 g of Ag produces 9.7 g of AgI
