How many grams of sugar (LD50 = 30 g/kg) would be lethal to a 220 lb woman?
A
6600 g
B
3000 g
C
0.30 g
D
0.13 g
Explanation: 

Detailed explanation-1: -The new LD50 formula ( LD 50 = ED 50 3 × Wm × 10-4 ) yielded value (0.29 mg/kg) of comparative significance with reported value (0.32 mg/kg).

Detailed explanation-2: -Sucrose’s LD50 is 13.5 grams per pound, and with the average person weighing 180 pounds, consuming 2, 440 grams (or 5.4 pounds) of sugar can be lethal.

Detailed explanation-3: -So, the example “LD50 (oral, rat) 5 mg/kg” means that 5 milligrams of that chemical for every 1 kilogram body weight of the rat, when administered in one dose by mouth, causes the death of 50% of the test group.
