How to make HCL 4% solution (MMS activation) - Solution MUST be 4%

Hi CLO2,
How did he get 107 grams of water?  8.25 x ? perhaps?  I am making a 6 oz bottle of 37% HCL.  From the dilution calculator I rounded up to 19.5 ml of HCL for the 180 ml for 6 oz bottle.  Then 19.5 x 1.19 = 23 grams of HCL.  I would take out 19.5 ml/gram of water to equal 100%?  Thanks, for helping me to understand this!

You are starting with 37% HCL to dilute down to 4% HCL? How much 4% HCL do you want?

A 6 oz bottle.  Does that make sense?  I think I understand how to get the amount of HCL, but don't understand how to get the amount of water. ...Finally got it.  i wasn't adding it correctly.
