Expert Solution
For the calculation of the millimoles (n) = weight of the particular compound in milligrams/ molecular weight
density and weight relationship is density = mass of the particular compound/ volume of the compound, for this one can calculate the volume of the liquid compounds.
For solid compounds like magnesium and benzophenone no need to calculate density.
The boiling point of the product triphenylmethanol is 162
0C.

Acetic acid (molecular weight = 60.05 g/mol) and sodium acetate
(molecular weight = 82.03 g/mol) can form a buffer with an acidic
pH. In a 500.0 mL volumetric flask, the following components were
added together and mixed well, and then diluted to the 500.0 mL
mark: 100.0 mL of 0.300 M acetic acid, 1.00 g of sodium acetate,
and 0.16 g of solid NaOH (molecular weight = 40.00 g/mol).
What is the final pH? The Ka value for acetic acid...
