here is the problem i m stuck on.. can someone help me get the answer..
i m really more interested then the work then the answer.
Convert 8.2mg/mL to (micro)g/L
Ooh delightful, a question in metric! That doesn't often happen round here. Full marks to the teacher.
There's 8.2 mg in every mL. There are 1000 mL in each L. So there's 1000 times as many mg in every L as there are in every mL. So multiply the 8.2 by 1000 to get the number of mg in every L.
Then there are 1000 microg in every mg. So there's 8.2 x 1000 microg in every mL. So theres 8.2 x1000 x1000 microg in every L.
Does that help?
not really.. its hard for me to understand it without math.. this is how i do it and i m getting the way wrong answer:
(8.2mg/1ml) x (10^-3 g / 1mg) = .0082g
.0082g/1 ) x ( 1 microg / 10^-6) = 8200
i m way wrong, but u see the way i do it.. can u show me that way how u got ur answeR??
Convert 8.2mg/mL to (micro)g/L
write it like a grid to solve the conversion problems here.
Then since there is 1000 (mL) in 1 (L) and you need to cancel the (mL), put it on topCode:8.2 mg | -------+ 1 mL |
Same for mg to (micro)g. There are 1000 (micro)g in 1 mg. mg goes on bottom to cancel the one already on top.Code:8.2 mg | 1000 mL | -------+---------+ 1 mL | 1 L |
The horizontal line is devide and vertical lines become multiply. The mg and mL cancel and the proper units remain in the proper place.Code:8.2 mg | 1000 mL | 1000 (micro)g | -------+---------+---------------| 1 mL | 1 L | 1 mg |
yes thank you every1! i got it ! ty alot.
here is what i did:
8.2mg/1mL (1mL / 10^-3 L)(10^-3 g/1 mcg)= 8.2 g/L
8.2g/L (10^6 mcg/1g) = 8.2 x 10^6
is what i did logical? i got the right answer though!
