Consider the reaction sequence from PP to QQ shown below. The overall yield of the major product QQ from PP 7575 % . What is the amount in grams of QQ obtained from 9.3mL9 . 3mL PP? (Use density of =1.00g mL−1;= 1 .00 {\text{g mL}}^{- 1}; Molar mass of C=12.0,H=1.0,O=16.0C = 12 .0 , H = 1 .0 , O = 16 .0 and N=14.0gmol−1N = 14 . 0g{mol}^{- 1})

Correct answer

0

Step-by-step solution

Consider the reaction sequence from P to Q shown below. The overall yield of the major product Q from P 75 % . What is

⇒Molar mass of′P′(C6H7N)=93g⇒ \text{Molar mass of} ' \text{P} ' \left({\text{C}}_{6}{\text{H}}_{7}\text{N}\right) = 93\text{g}

⇒Moleof′P′=(9.3gml×1ml)×193g=0.1mole⇒ Moleof ' P ' = \left(\dfrac{9 .3 g}{ml} \times 1ml\right) \times \dfrac{1}{93g} = 0 .1 mole

⇒⇒ Molar mass of ′Q′=248g' Q ' = 248\text{g}

⇒⇒ Mole of ′Q′' Q ' produced = 0.1mole0 . 1mole

Mass of ′Q′' Q ' produced =(0.1×248×0.75)g=18.60g= ( 0 .1 \times 248 \times 0 .75 ) g = 18 .60 g
