Material Calculator - Percentual Mixture

A calculator for amount and percent of a mixture of different substances. Up to five substances can be entered. The amount can be something like mass, weight, volume or number, the percent refer to this size. Please enter amount and percent of one substance and one of these values of the other substances. Each remaining value, the rest and the total will be calculated. Take care not to exceed 100 percent, otherwise the rest will become negative.

Example: You want to create a five percent saline solution with 8 grams of salt. Then enter at one substance Amount 8 and Percent 5 and press Calculate. The result for the rest, for example for the solvent water, is 152 grams and 95 percent, giving you a total of 160 grams of saline solution.

Another example: for a food consisting of various ingredients, you aim for a content of 30 percent fat, 12 percent sugar and 15 percent protein. The approximate densities of around 0.9 grams per cubic centimeter for fat, 1.6 g/cm³ for sugar and 1.35 g/cm³ for protein result in masses of 9, 16 and 13.5 grams respectively. Then you need 12.9 grams of one or more substances that contain neither fat, sugar nor protein for the rest to produce 51.4 grams of the combined food. These values ​​can be extrapolated; for 100 grams of the food, each individual amount is multiplied by 100 divided by 51.4, which is about 1.95. In reality, the calculation is usually more complicated, as fat, sugar and protein are usually not added in their pure form, but as components of other things.

One prerequisite for this calculation to be correct is, of course, that the substances do not react chemically with one another, because otherwise you will get completely different substances that are formed from the previous ones.
