                        Diluent calculation

                        • [Diluent amount] = [Final Volume] - SUM[Volume of all ingredients]

                        Ingredient amount calculation

                        All liquid ingredients (except the unit %(w/v))

                        • [Ingredient amount] = [Final concentration] * [Final Volume] / [Initial concentration]

                        Liquid ingredients, unit %(w/v)*

                        • [Ingredient amount] = [Final concentration] * [Final Volume] / 100

                        * This formula is used when you want to measure a liquid ingredient by weight, for example in the case of very viscous components like concentrated glycerol or tween20.

                        Solid ingredients, molar concentration.

                        • [Ingredient amount] = [MW] * [Final concentration] * [Final Volume]

                        Solid ingredients, w/v concentration

                        • [Ingredient amount] = [Final concentration] * [Final Volume]

                        Solid ingredients, % (s) concentration

                        • [Ingredient amount] = [Final concentration] * [Final Volume] / 100
