To convert an amount from milligrams to milliequivalents, convert the amount given into millimoles by calculating the atomic weight and dividing it by the amount of the substance in milligrams. Then, multiply the amount in millimoles by the valence number to get the amount in milliequivalents.
Know MoreThe periodic table is used to determine the atomic weight of a given substance. For example, if you are asked to convert 300 milligrams of sulfate to milliequivalents, you would look at the atomic weight listed for each element and add the numbers together. The formula for sulfate is SO4^--, so the atomic weight is 32 + (16 * 4) = 96 grams per mole. Since the conversion rate for grams per mole to milligrams per millimole is 1:1, the atomic weight in milligrams per millimole is 96.
Divide the amount of the given substance by its atomic weight. For 300 milligrams of sulfate, the result is 300 milligrams divided by 96 milligrams per millimole equals 3.125 millimoles.
If the substance being converted is a cation or anion, multiply its amount in millimoles by the number of charges to determine the amount in milliequivalents. If there is no charge on the substance, the amount in millimoles is the milliequivalent. Sulfate is an anion with a -2 charge, so the final equation is 3.125 millimoles * 2 = 6.25 milliequivalents.
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 >Milligrams are a measurement of weight, and teaspoons are a measurement of volume, so it is not possible to directly convert an amount between them. It is necessary to know the density of the material being measured to convert its amount in milligrams to teaspoons. For example, the density of water is 1 gram per milliliter, and 0.2 grams of water equals 0.2 milliliters, which is 0.04 teaspoons of water.
Full Answer >The weight of 12 fluid ounces depends on the density of the substance. Twelve fluid ounces of milk weighs 33.94 ounces, but 12 fluid ounces of pure water weighs 12.52 ounces. Salt water weighs 12.84 ounces due to its lower density.
Full Answer >The difference between mg and mcg is in terms of value, with 1 mg being equivalent to 1000 mcg. These abbreviations stand for milligram and microgram respectively.
