The ones we are always familiar with are units that are used to measure the length of an object. These are the millimeter, centimeter, inches, and meter.
For greater distances, we are familiar with miles and kilometers. For measuring weight, we usually know about kilograms and pounds. Every single object on this planet can be measured. Through the advancement of technology, scientists were able to add and modify these units of measurement. They were also able to measure even the tiniest cell structures through the nanometer.
From measuring our waistlines, our height, our weight, these are important values for our well-being. Engineers and other professionals also rely on this system of measurements. These two units of measurement are used for measuring the amount of a substance.
The volume in question is often a solution , which involves a substance called a solute in this context dissolved in a liquid called a solvent.
When solid dissolves in a solvent to create a solution, the concentration of the solution can be expressed in a variety of ways. This relates to the fact that chemicals react with each other not on the basis of mass but on the basis of the ratio of individual "pieces," regardless of size. The concept of moles and equivalents, and thus millimoles and milliequivalents , underlies this relationship, and it is of vital importance in medicine and clinical pharmacology. In an example of a simple chemical reaction, one atom of potassium K can react with one atom of chlorine Cl to form a molecule of potassium chloride KCl with nothing left over.
But this is not because potassium atoms and chlorine atoms have the same mass. Instead, it is because K and Cl react in a 1-to-1 molar ratio. A mole consists of 6. Every element's molar mass , or the mass of a single mole in grams is given in the periodic table of elements see the Resources for an online version.
This movement can be accomplished by facilitated diffusion and active transport. Facilitated diffusion requires protein-based channels for moving the solute.
Active transport requires energy in the form of ATP conversion, carrier proteins, or pumps in order to move ions against the concentration gradient. In order to calculate osmotic pressure, it is necessary to understand how solute concentrations are measured. The unit for measuring solutes is the mole.
One mole is defined as the gram molecular weight of the solute. For example, the molecular weight of sodium chloride is Thus, one mole of sodium chloride weighs The next step is to separate the formula into atoms.
Is mEq the same as ML? One mEq is equal to , of the gram-equivalent weight GEW of a solute. How many mL are in a mEq? How many mEq of potassium are in 15 mmol of potassium phosphate? What is a mEq of potassium?
The potassium chloride extended-release tablets, USP 20 mEq product is an immediately dispersing extended-release oral dosage form of potassium chloride containing mg of microencapsulated potassium chloride, USP equivalent to 20 mEq of potassium in a tablet.
Potassium chloride is an electrolyte replenisher. What unit is potassium measured in? See child's lab report for reference range.
