Consider the reaction sequence from P to Q shown below. The overall yield of the major product Q from P 75 % . What is the amount in grams of Q obtained from 9 . 3 mL P ? (Use density of = 1 .00  g mL − 1 ; Molar mass of C = 12 .0 , H = 1 .0 , O = 16 .0 and N = 14 . 0 g mol - 1 )

Correct answer

0

Step-by-step solution

⇒ Molar mass of ' P ' C 6 H 7 N = 93 g ⇒ Mole of ' P ' = 9 .3 g ml × 1 ml × 1 93 g = 0 .1 mole ⇒ Molar mass of ' Q ' = 248 g ⇒ Mole of ' Q ' produced = 0 . 1 mole Mass of ' Q ' produced = ( 0 .1 × 248 × 0 .75 ) g = 18 .60 g
