Question

Ritalin is the trade name of a drug, methylphenidate, used 
to treat attention-deficit/hyperactivity disorder in young 
adults. The chemical structure of methylphenidate is 
 
(c) Ritalin has a half-life of 3 hours in the blood, 
which means that after 3 hours the concentration in the 
blood has decreased by half of its initial value. For the 
man in part (b), what is the concentration of Ritalin in 
his blood after 6 hours?

Accepted Answer

Hey everyone. So as consider a person that drink alcohol in the bar and as much of that they have 1. g total of ethanol In the average blood bottom for the height is 4.5 l and the concentration of alcohol is halved every four hours. Whereas calculate the concentration of alcohol In terms of malaria. T after eight hours. All that. The similarity was the malls of the salute wanted by the leaders of the solution. We need to first find the moles of ethanol using the total mass and the molar mass of 1.35 g afternoon And in one mole at the nob of the molar mass, which is to 12.011 g six has 1.008g Plus 15.999 g. Just give us 46.07 g. We're going to get 0.02 93 moles at the nob. An advocate is the most ethanol in the final of the solution. To find the clarity. 0.02 93 moles. About 4.5 L. I'm gonna get $0.0065. And we know that after four hours it is half after another four hours we have it again. This means that by the malaria before we can have 0. smaller, about four. And this gives us 0.0016 smaller. Thanks for watching my video and I hope it's up for
