The mass of silver (Molar mass of Ag : 108 gmol - 1 ) displaced by a quantity of electricity which displaces 5600 mL of O 2 at S.T.P. will be _____ g.

Correct answer

0

Step-by-step solution

Given Molar mass of Ag : 108 gmol - 1 Equal equivalents of substances deposited or liberated when some quantity of electricity passed through circuite in the electrolysis cell. Equivalents of silver deposited= Equivalents of O 2 liberated. Let x gm silver displaced, (Molar volume of gas at STP = 22 . 4 L ) Number equivalents of a substance = The number of moles of substance × Valence factor of that substance x × 1 108 = 5 . 6 22 . 4 × 4 , x = 108 gm .
