(9.3 ~g ) of pure aniline upon diazotisation followed by coupling with phenol gives an orange dye. The mass of orange dye produced (assume 100 % yield/conversion) is _______ g. (nearest integer)

Step-by-step solution

Reaction suggests that 1 mole of aniline give 1 mole of orange dye. aligned & so ( mol )_ aniline =( mole )_ orange dye & 9.3 ~g 93 ~g ~mol ⁻¹ = mass of orange dye 199 ~g ~mol ⁻¹ aligned mass of orange dye =19.9 ~g 20 ~g
