The mass of ( AgCl ) precipitated when a solution containing ( 11.70 ~g ) of ( NaCl ) is added to a solution containing ( 3.4 ~g ) of ( AgNO ₃ ) is [Atomic mass of ( Ag =108 ), Atomic mass of ( Na =23 ) ]

Options

  1. A( 2.87 ~g )
  2. B( 6.8 ~g )
  3. C( 5.74 ~g )
  4. D( 1.17 ~g )

Correct answer

A. ( 2.87 ~g )

Step-by-step solution

Balanced reactio is: ( NaCl + AgNO ₃ AgCl + NaNO ₃ ) molar mass of ( AgNO ₃=170 ~g ) molar mass of ( NaCl =58.5 ~g ) molar mass of ( AgCl =143.5 ~g ) from the reaction (58.5 ~g NaCl ) reacts with (170 ~g AgNO ₃ ) thus (5.85 ~g NaCl ) will reacts with (= 170 58.5 5.85=17 ~g AgNO ₃ ) Given ( AgNO ₃=3.4 ~g ) therefore ( AgNO ₃ ) is completely consumed and is the limiting reagent (170 ~g AgNO ₃ ) produces (143.5 ~g AgCl ) (3.4 ~g ) will produce (= 143.5 170 3.4=2.87 ~g AgCl ) Hence, option A is correct.
