Amedication is given at a dosage of 3.000 mg of medication per kg of body weight. of 0.1500 g of medication is given, then what was the patient's weight in pounds ( report answer to 1 decimal places.

110.2 lbs  
First, let's determine how many kg the patient masses. Since the dose is 3.000 mg/kg we can convert that to 0.003000 g/kg. So 
0.1500 g / 0.003000 g/kg = 50 kg.  
So we know the patient has a weight of 50 kg. Now we simply multiply by 2.20462 to get lbs. So 
50 kg * 2.20462 lbs/kg = 110.231 lbs  
Rounding to 1 decimal place gives 110.2 lbs
