| 21% sodium ethoxide in ethanol | 68.05 g/mol | 0.868 g/mL | 20 mL | ~1.3 | |
| *1-bromobutane | 137.02 g/mol | 1.276 g/mL | 4.5 mL | ~1.0 |
*Limiting Reagent: 1-bromobutane
I need help finding the mmol of sodium ethoxide in ethanol and
1-bromobutane. Also how to find the theoretical yield of this
reaction from this graph?
