The balanced equation is below: Na + Cl --> NaCl What is the percent error of the student? To solve this first calculate the theoretical yield using a basic stoichiometry problem (See "Stoichiometry"). you get 6.7 now take 6.7 and divide it by 31.2 and you get an answer now multiply by 100 and that is your error percentage. =21.5% Margaret · 8 months Percent Error Worksheet So based off of the problem above, the percent yield would be 86.90% (12.6 / 14.5) * 100 = 86.90%.
