Part Ci Determination of Mass Pereent of Silieen diaxile (Si02) Mans ef evaporating dish and 50 Mais of evaperating diah Mass of SiOl7 Persent ef 50x. Calculations: Part D. Deteemination of Percent Recovery Mass of oeiginal sample (frem Part A ) Mass determined (Fe + NaCl+siO2 recovered) Pertent tecevered Mhass determined (ie + NaCl+SiO j reconered Fercent tecovered Calculations: If you did not recover 100k, account for your eerors. What are some reavam your percent. fecovered is less than 1005 or more than 100%? Lab Report Sheet: Part A: Determination of Mass Percent of Iron (Fe) Mass of evaporating dish and unknown sample Mass of evaporating dish Mass of original sample Mass of evaporating dish after removing iron fillings Mass of Fe Percent of Fe in sample Calculations: Part B: Determination of Mass Percent of Sodium Chloride (NaCI) Mass of (NEW) evaporating dish, watch glass, and NaCl Mass of evaporator dish, watch glass Mass of NaCl Percent of NaCl Calculations: Part C: Determination of Mass Percent of Silicon di) Mass of evaporating dish and SiO2 Mass of evaporating dish Mass of SiO2 Percent of SiO2 Calculations: Part D: Determination of Percent Recovery Mass of original sample (from Part A) Mass determined ( Fe+NaCl+SiO2 recovered) 8 Percent recovered 6 Calculations: If you did not recover 100%, account for your errors. What are some reasons your percent recovered is less than 100% or more than 100% ?
