                    (C6H5)2 C2H2Br2   +    KOH    ---------------->    (C6H5)2 C2

general            340g                                                               178.22g

Given              0.75g                     0.75g                                  0

Here triethylene glycol is a solvent and KOH is excess reagent

340g 1,2-dibromo-1,2-diphenylethane can from 178.22g diphenyl acetylene.

0.75g 1,2-dibromo-1,2-diphenylethane can from 178.22*0.75/340=0.3931g diphenyl acetylene.

3.00 g of potassium hydroxide (KOH) pellets are put into a constant-pressure calorimeter containing 250 mL of water. The initial temperature of the water is 22.3°C. The mixture is then stirred until all of the KOH is dissolved. The final temperature of the solution is measured and recorded as 29.7°C. Calculate the heat of solution for potassium hydroxide (ΔHsoln). The specific heat capacity of the solution may be assumed to be the same as that of water since this is...
