If have a container with a capacity of 5,000 cubic inches, how do I calculate the ratio of 50 ppm? I would describe the problem as,
a/b = 50/1,000,000 a = ? b = 5,000
2.) show your work,
Establish the ratio of the ppm ratio and "to be scaled"* volume
50/1,000,000 = a/5,000
a1,000,000 = 50*5,000 a = .25
3.) the full answer,
The fraction of liquid (a) to liquid (b) is 0.25 cu. in. of liquid (a), to 5,000 cu. in. of liquid (b).
4.) Check my work,
(0.25/5,000) = 0.00005 = (50/1,000,000)
Is this correct? Is there a simpler way?
* I'm making this ratio fraction problem simple and not using the "total" volume.
