A certain quantity of electricity deposits 0.54 g of silver from A g N O 3 solution. What volume of hydrogen will the same quantity of electricity liberate at 27 ° C and 750 mm Hg pressure?

Options

  1. A62.34 ml
  2. B6.234 ml
  3. C623.5 ml
  4. DNone of these

Correct answer

A. 62.34 ml

Step-by-step solution

W A g E A g = W H 2 E H 2 or 0.54 108 = W 112 1 W H 2 = 0.005 g P = 750 mm = 750/760 atm Using ideal gas equation V = W R T M P = 0.005 × 0.082 × 300 × 760 2 × 750 = 62 .34 ml .
