Solution:
Since our final answer should be expressed in grams, let us convert all units into grams.
1000g = 1kg
Converting 65.7kg to g = 65.7 x 1000 = 65700g
73ap/lbs;
1lb = 453.6g
73ap/lbs x 
= 0.161ap/g
Now,
For a 65700g person, the number of grains app required;
65700 x 0.161 = 10,573.4grains ap per dose
