You need to  measure  the volume and  density after and before adosrption and use the pubblished tables to calculate the conecntration  and the make mass balance as you pointed out

Hi All,
 
I finally found a source of 3A molecular sieve. It´s been sitting in 95% ethanol overnight. How do I test the ethanol to see if I removed the 5% water? Simple mass balance? I don´t have a Karl Fisher titrator. BTW, I used the recommended 250 grams of 3A per liter of ethanol.
 
Thanks,
 
Tom Irwin
