Question

A commercial package contains thirty-six 200-mg tablets of ibuprofen. How many kilograms of ibuprofen were

Answer 1

Answer: 0.0072 kilogram

Explanation:

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

Then, the mass of 36 tablets of ibuprofen =
`36*200` 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}=(1)/(1000,000)\text{ kg}`

Now,
`\text{7200 mg}=(7200)/(1000,000)=0.0072\text{ kg}`

Hence, A commercial package contains 0.0072 kilogram of ibuprofen.
