D Question 9 1 pts Sample % yield question: For the following reaction with the amount of reactants and molar masses given, if 14 g of C is produced, what is the % yield of this reaction? Answer to 2 sig figs. Sample input: if 20% is the correct answer, use 20 instead of 20%; do NOT use fraction such as 0.20 Molar masses: A-100 g/mol; C-200 g/mol Starting materials: A 10. g: B- In excess Question 10 1 pts Which of the following might be a contributing factor to low experimental purity of green crystals? O Forming the crystals too quickly by cooling it down in an ice-water bath O Over-titration O All of them will contribute to a low experimental %purity O Some green crystals are lost during filtration last week
