Chem math question!!

[From: ] [author: ] [Date: 11-05-26] [Hit: ]
How many people (assume average body weight of 150 lbs) would be killed if exposed to 250 grams of Sarin?It may be easy for others but math has never been my best subjct ! Please help if you can!-367,first what i did was convert the give grams to mg and the average weight to kg. then you devide your mg by your kg to get mg/kg.......
I had this question in chemistry that confused me a bit!

Sarin (C4H10FO2P) may have a lethal dose as low as .01 mg/kg. meaning that someone would die if exposed to .01 mg of Sarin for every kg of body weight. How many people (assume average body weight of 150 lbs) would be killed if exposed to 250 grams of Sarin?

It may be easy for others but math has never been my best subjct ! Please help if you can!

first what i did was convert the give grams to mg and the average weight to kg. then you devide your mg by your kg to get mg/kg. once you have that you multiply it by for give factor (.01mg/kg)

250g*(1000mg)= 250,000 mg 150lbg*( 0.453 592 37 kilogram)=68.038858
------------- ----------------------------------
1g 1lb

250,000mg = 3674 mg/kg
----------------
68.038858kg

3674mg 1kg 1 Person
----------- * ------------ * -------------- = 367,400 people
kg .01mg
