What is molarity in analytical chemistry? What volume must 25 ml of 95% by mass of a solution H2SO4,density 1.80 g/ml, be diluted to produce 0.5 M solution? What is density of water in g ml? How do you convert 4 liters to milliliters?
In chemistry, “mM” stands for millimolar, which is a unit used to express a solute’s concentration in a solution. 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...
What is a mixture in chemistry? Learn the types and properties of mixtures. Also, see various examples of mixtures. Related to this QuestionWhat is the osmotic pressure of a 0.25 M solution of NaCl at 25 °C? What is the mole, molality and osmolality of 0.9% NaCl and 3.5% NaCl?
Normality can also be described as thenumber of grams of mole equivalents of solutepresentin one litreof a solution. Normality is mainly used to determine the concentrations in acid-base chemistry, in precipitation reactions to evaluate the number of ions precipitated in any given reaction, and in...
