Here's a link to that UC Berkeley Webcast of an Intro to Chem semester:

I'm taking chem this fall and I need help. Our tutor center does not open until next week which is to late for any help with my homework. If any one can explain to me the step on how to solve this question I will be forever thankfull. The question is What dosage in grams per kilogram of body weight does a 130bl woman receive if she takes two 250mg tablets of penicillin? How many 125mg tablets should a 40lb child take to recieive the same dosage?

1Kg=2.21 lbs
so you would need to convert the weight to Kg first,
then the dosage will be much easier to figure out

Okay Love316 this is how we solved a simular problem in my CHEM class. I'm assuming that the dosage is in mg's

You need to get rid of lbs so you start with

130 lbs X 1 kg X Xmg = 500 mg
---------2.205lb 1 kg


The lbs cross out and the kg's cross out and now you just solve for X.
I got 58.9.X = 500 mg
X= 8.48 mg plugged in it is =499.9 =500.

If doing for the child I think you just plug it in.
40 lbs X 1 kg X 8.48 = Xmg
---------2.205 1 kg 125mg p/tablet


I got 154 mg divided by 125 mg = 1.23 tablets

The spaces are not showing the fractions: 1 kg should be over 2.205 lbs and Xmg should be over 1 kg.

I hope this helps and I hope this is right. I'm going to have my professor look this over tomorrow.

Well, I have to say, I LOVE my instructor. She is fabulous and has a lot of energy. While she is fab, I know that if I don't do okay in her class, it is NOT the instuctor. LOL. I am hoping for a B.

As of right now, we are just working w/ dimensional analysis and spending lots of time w/ it. I am having the worst time w/ making the "bridges." I don't know off the top of my head how many meters are in a mile and so on.

I told my class that I will pray myself through Chem. LOL

Chemistry is actually pretty interesting this semester. The teacher actually explains the chapter's and doesnt feel that we should now all of the information beforehand! Im shooting for an A!
