3.75ml.

I used eJuiceMeUp's Nic combiner. Input 7.5ml of 0mg as Nicotine Base 1. Input 48mg into Nicotine Base 2. Input different values into the ml box until I hit 16mg combined.

+3ml resulted in 13.71mg/ml.
+4ml resulted in 16.70mg/ml.

Used that to fine tune until I hit 16mg on the dot.

I'm sure there are easier ways, but there you go.
