Need algorithm to fill Capsule

I have a program that I am writing that will fill capsules to a desired level. For this example we will be filing a 0.3 ml capsule. This capsule will be filled from 3 different reservoirs but algorithm should not be limited to only 3 reservoirs. User enters in ingredients information: Reservoir 1 has the following ingredients: Active ingredient Material: THC Dosage: 25 mg Purity: 75% Density: 1.3 g/cm3 Inactive ingredient Material: Filler Purity: 99% Density: 5 g/cm3 Reservoir 2 has the following ingredients: Active ingredient Material: CBD Dosage: 50 mg Purity: 45% Density: 1 g/cm3 Inactive ingredient Material: Filler Purity: 99% Density: 1 g/cm3 Reservoir 3 has the following ingredients: Active ingredient Material: Vitamin c Dosage: 10 mg Purity: 50% Density: 3 g/cm3 Inactive ingredient Material: Filler Purity: 99% Density: 3 g/cm3 * Note * These are only examples these ingredients can change and there could be more or less reservoirs Final Capsule Capsule Size: 0.3ml THC - 25mg CBD - 50mg Vitamin C - 5mg Algorithm will fill 80 capsules per run. I am looking for an algorithm that can give me the following information: Active ingredients in grams per reservoir Inactive ingredients in ml per reservoir Dispense per capsule per reservoir I am looking to have this algorithm written in c#
