Polymer mixture - gallons to Lbs?

[KWTPOP]

I have a mixture of 7.5 ml Polymer to 1 gallon of water. how do I calculate the gallons used into lbs? I was given the fomula of Polymer gallons used times .016 but that doesn't look right. In the case of say Alum, it is the gallons used times 5.4.

This should be a very easy conversion, but you have worded your query badly. You sometimes talk of "gallons of water", sometimes of "Polymer gallons" and sometimes just "gallons used". I cannot determine what you actually want to calculate. Also we do not know where you are - are you using US gallons or Imperial gallons?

Sorry. I am using U.S. gallons. What I should have asked was per gallon of water, what is weight of the polymer in the mixture? The more I look at it, the more it looks like the gallon x .016 may be correct. Thanks for responding.

If the SG of your polymer is 1.0 then 7.5 ml would have a mass of 7.5 gram. And 7.5 gram is equivalent to 0.016 lb so it looks like your number is correct.
