How I do it
by: Pharm Tech

The c1 v1 = v2 v2 works here.

You know the % strength of first product 6% or .06, but you don't know the volume.. X. The second product is 1 pound or 454 grams and its 2% or .02.

So setup we get (.06)(x)=(454)(.02)
= 151.333333333 grams

I got 2 different answers with different formulas
by: Anonymous

When I did this problem with the formula
(c1)(v1)=(c2)(v2) I got 1362gm which is 3Lbs.
When I just cross multiply I get what you got 151.

Sorry I'm not sure what the right answer is.

Hope someone can explain it better.
