Bottle A = 25ml
Bottle B = 25ml
Add half of each to 150ml bottle (12.5ml x 2).
150ml - 25ml = 125ml Distilled water to fill
Bottle A = 5ml
Bottle B = 5ml
Add 5ml of A and B, mix, add 25ml-28ml of Distilled water
Is this the same ratio? Ugh…I feel like a regard.
1A&B combined stock solution:5 Distilled water…am I close?..lol
