Question

please help. need a proper explanation with it to pass :(

Answer 1

$%age Yield = \frac{Actual Yield}{Theoretical Yield}$Answer:

             Percentage Yield = 127.5 %

Explanation:

Percent Yield is given as,

$%age Yield = \frac{Actual Yield}{Theoretical Yield} x 100$$%age Yield = \frac{Actual Yield}{Theoretical Yield} x 100$%age Yield = Actual Yield / Theoretical Yield x 100

Putting values for Sodium Carbonate,

%age Yield = 2.04 g / 1.60 x 100

%age Yield = 127.5 %

Note: Percentage yield can never exceed 100%. This means the product obtained is impure. Due to contamination the actual yield is greater than theoretical yield.
