Amedication is given at a dosage of 3.000 mg of medication per kg of body weight. if 0.1700 g of medication is given, then what was the patient’s weight in pounds ( use significant figures. do not enter “lbs” as part of your answer. do not use scientific notation

We will find out first the mass of the person in kilograms like this:
3000 mg .......................................................... 1 kg
170 mg (0.1700 g) ........................................... x kg
=> 
The mass in pounds will be 0.05 * 2.204 = 0.124 pounds as 1 kg is equal 2.204 pounds. So the answer is 0.124 .
