You have a tank of wine that needs a 20 ppm addition of SO2.

1. To make 5 gallons of a 6% w/v SO2 solution (expressed as SO2) how much K2S2O5 (222 g/mol) should be weighed out?

2. How much of this solution (in mLs) should be added to the tank (wine is 73 inches high in the tank, 11.4 gallons/inch)?
