Question

You must use reference materials such as the CRC Handbook or an Aldrich catalog (or try Google to find online resources) to find the physical properties of each reagent. Several calculations must be performed to complete the rest of the Reagent Table. The Reagent table page of the prelab is turned in to the instructor at the BEGINNING of each lab. Below, you, find a sample reagent table so you can practice the required calculations. You should be able complete the missing data, as indicated by empty boxes. * This box is for the Theoretical Yield (TY). It can be calculated by first determining which reagent is the limiting reagent. The TY Amount in this example should be calculated in both grams and mL (for liquid products). Show your work here and include units in your calculations:

Explanation / Answer

No. of moles = mass /molecular mass = volume* density / molecular mass

2 bromoaniline no. of moles = 2ml * 1.56 g/ml / 172 g/mol = 0.01814 moles   Answer

NaNO2   no of moles = 1.9 g / 69 g/mol = 0.02754 moles of NaNO2    Answer

KI no of moles = 3.6 g / 166 g/mol = 0.02169 moles of KI         Answer

so here 2 bromoaniline is limiting reactant

No. of moles of 2 iodobromo benzene formed = 0.01814 moles           Answer

mass of 2 iodobromo benzene formed = No. of moles * molar mass = 0.01814 moles * 283 g/mol

= 5.134 g Answer *

Volume of 2 iodobromo benzene formed = mass / density = 5.134 g / 2.2 g/ml = 2.33 ml answer *
