Question

Assume you started with a 0.642 gram sample of Sodium Bicarbonate and aster adding an excess of hydrochloric acid and carrying out the experiment correctly, you calculateed there was a 94.8% yield of sodium chloride. What was the experimental yield of sodium chloride in the experiment?

I did get the theoretical yield of sodim chloride? I got 0.3115g

Please help me

Answer 1

The question is worded poorly. I assume you want to calculate the GRAMS of NaCl produced in the experiment with a 94.8% yield.
%yield =(actual yield/theor yield)*100
98.4 = (actual/theor)*100
0.984 = actual/0.3115
Solve for actual yield

Answer 2

yes i do understand that 0.3115 us the actual yield the theoretical yield but i need the the experimental yield of soduim chloride

Answer 3

That's the actual yield.
Theoretical yield is 0.3115 and I'm assuming that is correct.
% yield is 98.4% of that; therefore, experimentally you will collect 0.984 x 0.3115 g = ? grams NaCl.

1. Potassium, a silvery metal, reacts with bromine, a corrosive, reddish liquid, to yield potassium bromide, a white solid. Write the balanced equation, and identify the oxidizing and reducing agents.
