6. (25 pts) (a) Calculate the theoretical yield, (b) limiting reagent, and (c) percent yield of the above reaction if you were to react 48 mmol of 1-Butanol with 60 mmol of aqueous hydrobromic acid and you obtained 4.1g of 1-Bromobutane? SHOW ALL CALCULATIONS (a) Theoretical Yield: (b) Limiting Reagent: (c) Percent Yield:
The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to product. Consider the reaction: 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) If 16.98 g Fe is mixed with 7.740 g O2, calculate the theoretical yield (g) of Fe2O3 produced by the reaction.
Trying to calculate Theoretical yield but I think I need the moles of the limiting reagent. I thought I needed density if only the limiting reagent was in mL. Need help. Thanks in advance Synthesized 2-chloro- Zmethyl butane starting with 10 mb of 2-chloro- 2 methyl butanol. The reaction yielded a product of 9.4312 g Calculate percent yield. Molar Mass of 2-chloro-2 methyl butanol. 10ml 122.59 g/mol C5H, CIO Molar Mass of 2-chloro-2 methyl butane 106.59 g/mol Cs Huch
The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to product. Consider the reaction: 2 CO(g) + O2(g) → 2 CO2(g) If 11.82 g CO is mixed with 9.180 g O2, calculate the theoretical yield (g) of CO2 produced by the reaction.
The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to product. Consider the reaction: CH4(g) + CCl4(g) → 2 CH2Cl2(g) If 17.38 g CH4 is mixed with 13.50 g CCl4, calculate the theoretical yield (g) of CH2Cl2 produced by the reaction.
