7B.1 mass of drug left in body

Postby Hannah_1G » Fri Mar 13, 2020 8:51 pm

Does the initial mass of the drug replace the concentration in the rate law equation for solving for the left over mass?
Would I use this equation in 7B.1 to solve for how much drug is left?

Yes, the initial mass of the drug replaces the initial concentration in the rate law equation that you've provided. So, you could use this equation in 7B.1 to solve for how much drug (mass) is leftover. This will get you the correct answer.

Yes, you would use that equation by plugging in all the givens provided and find out that 10% of the initial concentration is in the body. Then you would multiply the mass times 0.10 to get the total mass of drugs remaining in the body.
