Answer:
23 grams NaOH with significant figures; 220 % yield
Explanation:
25 g CO2/44.01 g CO2*40.00 g NaOH = 23 grams of NaOH
% yield = (actual yield/theoretical yield)*100 = (50 g NaOH/23 g NaOH)*100 = 220 % yield
I rounded in the problem for when I wrote it down, but I left the original number in my calculator for solving for the percent yield. I think the percent yield sig figs are off because I do not know if you (the person asking) are allowed to put this in scientific notation to make this have the correct number of sig figs which is two of them.
