The atomic mass of the element concerned must be divided by the number of valence ions present in that element. The number of ions is calculated by multiplying the valence value of the element by the mass in milligrams of the element in question.Continue Reading
Each element has its own valence value. Aluminum, for example, has a valence value of 3, often represented as Al 3+. Consulting a table of valence values assists in this process. To find the number of ions in 10mg of aluminum, 10mg is multiplied by the valence value of 3 to give an answer of 30 ions.
The atomic mass of an element can be found by consulting the periodic table. In this example, the atomic mass of aluminum is 27.
Calculate the milliequivalents by dividing the atomic number by the number of valence ions. Here, 27 divided by 30 gives 0.9 milliequivalents in 10mg of aluminum.
In order to convert milligrams to milliliters, one must know the density of the substance; if the density is measured in milligrams per milliliter, the milligrams of mass of the object being measured are divided by the density of the substance to determine the volume in millimeters. Because density is generally not listed in milligrams per milliliter, it is likely that some calculations must be done to convert the density into the appropriate units.Full Answer >
The conversion of milligrams to milliliters is dependent on density and can be found using the formula volume = mass/density, where the volume is in milliliters, the mass in milligrams and the density in milligrams per milliliter. The various densities of different substances give different mass to volume ratios.Full Answer >
To convert milligrams (mg) to milliliters (ml), the number of milligrams must be multiplied by the density of the liquid, which equals the volume in liters,and then divided by 1,000 to convert liters to milliliters. The density of each liquid is unique.Full Answer >
A milligrams-to-grams chart is a table that lists the number of milligrams per gram. The chart provides a reference for converting between two units of measure for mass, grams and milligrams.Full Answer >
