PIT_PIT [208]

Answer: 0.0072 kilogram

Step-by-step explanation:

Given : The mass of one tablet of ibuprofen =200  mg

Then, the mass of 36 tablets of ibuprofen =36\times200  mg

i.e. the mass of 36 tablets of ibuprofen =7200  mg

We know that 1 kilogram = 1000 grams

and 1 gram = 1000 milligram

Then, 1 kilogram = 1000,000 milligrams

Then, \text{1 mg}=\dfrac{1}{1000,000}\text{ kg}

Now,  \text{7200 mg}=\dfrac{7200}{1000,000}=0.0072\text{ kg}

Hence, A commercial package contains 0.0072 kilogram of ibuprofen.
