There are 1000 mcg in 1mg

Dobutamine 1gram = 1000 x 100 = 100,000 mcg

Dobutamine 100,000 mcg in 250 mls

Dobutamine 100,000 mcg in 250 mls Now divide both mcg & mls by 250 to simplify=

Dobutamine 400mcg in 1 ml

That's really funny you say that you're from here... I am actually from New Orleans and just moved up here. Working at Mayo...

That town sounds familar but I'm still not sure about the area. How far away is Osseo?

So I guess we traded places :)

Anyway... still not sure about this problem...

I keep getting the 4000 mcg/ml

Oh well... sorry about the decimal confusion!

Osseo is just a little north of MPLS.

I have lived in Virginia for about 20 years now -

I love the heat and the summers here - and the mild winters.

The first line:

Dobutamine, 1 gram= 1000 x 100 = 100,000 mcg

should read:

Dobutamine, 1 gram= 1000 x 1000 = 1,000,000 mcg

That's why the correct answer is 4000, not 400. (I always like to know what went wrong.)
