Oh my. I guess everything else is okay. Thanks for your patience. I appreciate it!

I was trying to brief earlier. The first two paragraphs only talk about the start of the experiment and the lower layer. Reading the third will probably clarify everything. Benzoic acid/biphenyl mixture was a white powdery solid. It was 2.08g. It was dissolved in 30mL of diethyl ether in an...

The issue is, when I do Percent recovery right away. I get crazy answers. (0.9[benzoic acid] + 27.11[biphenyl])/2.08 x 100 = 1346 % Mass of RBF + boiling stones= 61.61g Mass of RBF + bioling stones + biphenyl = 88.72g Mass of biphenyl = 27.11g The biphenyl itself was very little in substance...

I've been trying to convert the benzoic acid/biphenyl to moles to find the limiting reactant, then comparing the number of moles in order to find percent recovery. But I cannot get the equation or the mass used to find theoretical yield since there is only one mass (2.08 g)

The mass of the benzoic acid/biphenyl mixture was 2.08 g. Biphenyl product was placed in a pre-weighed round bottom flask. I didn't take the measurement for the pre-weighed stuff, it was copied from a partner. Pre-weighed rbf was 61.61g. When I weighed it after leaving it alone, it was 88.72g...

Homework Statement Benzoic acid/biphenyl mixture is mixed with diethyl ethe(CH3CH2-O-CH2CH3). The solution is placed in a separatory funnel and sodium hydroxide is mixed in. The bottom layer, H2O, NaOH and benzoic acid is then placed in a flask where it is mixed with HCl, chilled and then...

10.4 g. The amount that was left dissolved in ethanol? Do you mean the 0.08 g? I'm not exactly sure what you're saying. Thanks for answering.

Homework Statement Compound A mass - 11.0g solubility in ethanol at 78 deg C - 0.53 g/mL solubility in ethanol at 0 deg C - 0.08 g/mL Impurity B mass - 2.5 g solubility in ethanol at 78 deg C - 0.82 g/mL solubility in ethanol at 0 deg C - 0.12 g/mL Impurity C mass - 2.5 g solubility in...
