A mole ratio is the ratio between the amounts inmolesof any twocompoundsinvolved in achemical reaction. Mole ratios are usedas conversion factorsbetween products andreactants in many chemistry problems. The mole ratio may be determined by examining the coefficients in front of formulas in a ...
In a recent issue of Chemistry International, Ian Mills and Martin Milton suggested a new definition for the mole, one of the seven base units.1This matter is controversial and needs a careful examination. The IUPAC Green Book2describes the seven base units and gives their definitions. They ar...
What Does “mM” mean in Chemistry? Explanation: Millimolar (mM) concentrations are often used for convenience when working with solutions of small quantities of substances. One millimolar (1 mM) is equal to one-thousandth of a mole per liter (1/1000 mol/L).If a solution has a 5 millimol...

What is mass ratio in chemistry? Stoichiometry: Stoichiometry refers to the calculations made to find amount of reactants and products in a chemical reaction. Stoichiometry is based on the law of conservation of mass, where the total mass of reactants will have to produce an equal amount of...
One mole is a scientific form of measurement in chemistry. Elements need to have equal amounts of protons and electrons to be stable, but they can vary in the amount of neutrons they contain. The amount of protons in the element is theatomic number. ...
