A: ### Quick Answer

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.

Know More**Establish the number of valence ions available**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.

**Find the atomic mass of the element in question**The atomic mass of an element can be found by consulting the periodic table. In this example, the atomic mass of aluminum is 27.

**Divide the atomic mass by the number of valence ions**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.

## What is 250 milliliters converted to milligrams?

A:For water, which has a density of 1000 milligrams per milliliter, the mass of 250 milliliters is 250,000 milligrams (250 grams). To find the mass of 250 milliliters of a substance in milligrams, one must multiply 250 by the density of the substance.

## What is the formula for converting milligrams per kilograms to parts per million?

A:

Full Answer >**The number of milligrams per kilogram is exactly the same as the number of parts per million.**In other words, 1 mg/kg = 1 ppm.Filed Under: - Q:
## How many milligrams are in one teaspoon?

A:The number of milligrams in 1 teaspoon varies according to the density of the substance being measured. Milligrams are a unit of weight; the teaspoon is a unit of volume equivalent to 5 milliliters. These measurements are part of the modern metric system established by the International System of Units.

## How do you convert mg to ml?

A:

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.Filed Under:
