Benzocaine:
C9H11NO2
1 mol is equal to atomic mass at grams.
1 mol C = 12 grams===> 9 mol = 12 x 9 = 108 grams C
1 mol H = 1 gram=====> 11mol= 11 grams H
1 mol N = 14 grams====> 1mol = 14 grams N
1 mol O= 16 grams=====> 2mol = 32 grams O
Then:
108 + 11 + 14 + 32 = 165 grams Benzocaine
If 1 mol Benzocaine—————————> 165 grams
then x mol ————————————-> 0.65 grams
x= 0.040 mol or 40 millimol
