For my theortical yield I got 1.1173 g
For my actual yield I got 0.27 g
I need to find my percent yield and percent error. Did I do this right?
% Yield = (0.27/1.1173) * 100
= 24 %
% Error = [(0.27-1.1173)/1.1173] * 100
= -76 %
Yes, that is done correctly. For the % error, I GUESS that's ok but I don't know that I would call it error. The yield is 24% of theoretical and that is 76% short of the mark. I've never heard it referred to as error. Whatever your prof wants there is what you put. Your calculation is ok.
Thanks so much !
To calculate percent yield, you divide the actual yield by the theoretical yield and multiply by 100. In this case, the actual yield is 0.27 g and the theoretical yield is 1.1173 g. So the percent yield is:
% Yield = (0.27/1.1173) * 100 = 24.2%
So you calculated the percent yield correctly.
To calculate percent error, you subtract the theoretical yield from the actual yield, divide the result by the theoretical yield, and multiply by 100. In this case, the actual yield is 0.27 g and the theoretical yield is 1.1173 g. So the percent error is:
% Error = [(0.27 - 1.1173)/1.1173] * 100 = -76.05%
So you calculated the percent error correctly as well.
However, it's important to note that a negative percent error is possible when the actual yield is less than the theoretical yield. The negative sign indicates that the actual yield is lower than the theoretical yield. In this case, the percent error of -76% means that the actual yield is about 76% lower than the theoretical yield.
