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 MoreEach 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.
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 >Radians measure angles as the arc length of a circle subtended by an angle, divided by the radius of the circle. Each radian is equal to approximately 57.3 degrees, and there are approximately 6.28 radians in a full circle.
Full Answer >Since one centimeter is equal to 0.3937 of an inch, 64 inches can be divided by 0.3937 to be converted to 162.56 centimeters. There are free unit converters available online that can perform this calculation automatically, as well.
Full Answer >You can convert any centimeter measurement to millimeters by remembering that there are 10 millimeters in 1 centimeter. Anytime you need to convert from centimeters to millimeters, simply multiply the centimeter value by 10.
