C6H5NH2 + (CH3CO)2O = C6H5NHCOCH3
1 mole 1 mole 1 mole
10g
mol wt of aniline 12x6 + 1x5 + 1x14+1x2=93
no of moles of aniline = wt/ mol wt
= 10/93=0.1075moles
1 mole aniline can gice 1 mole acetanilide
0.1075 mole can give = 0.1075mole
wt of acetanilide= no mole xmol wt of acetanilide
mol wt of acetanilide 6x12+5+14+1+12+16+12+3= 135
wt of acetanilide= 0.1075 x 135
=14.51 g
