determine the empriical fornula of warfarin, a rodenticide which consists of 74.01% C, 5.23% H, and 20.76% o by mass

Explanation:

C = 74.01 %

H= 5.23 %

O=20.76 %

Ratio of moles of C , H , O

= 74.01 / 12 : 5.23 / 1 : 20.76 / 16

= 6.1675 ;5.23 : 1.2975

= 4.75 : 4.03 : 1

= 4.75 / .25 : 4.03 / .25 : 1/.25

= 19 : 16 : 4
