The concentration of the substance is the amount of the substance present in the total amount of solution. It can be measured in different ways such as molarity, molality, mass percent, mole fraction, etc. Answer and Explanation: Molality is defined as the number of moles of solute present...
The relative lowering of pressure and lowering of pressure are colligative property. ... As per Raoult's law, which states that the lowering in vapour pressure of a dilute solution is equal to the mole fraction of the solute in the solution.p∘–pp=nn+N. Here, n is the moles of the...

Australia had a hand in fashioning the roundest macroscopic object on the Earth, a silicon sphere used to measure theAvogadro constant, the number of entities in a fixed amount of substance. This now defines the SI unit, mole, used largely in chemistry. ...
Both radicals show the same stoichiometry with water-soluble vitamin E analogue, Trolox (e.g., two moles of ABTS•+ [26] or two moles of DPPH radicals [27] are scavenged by one mole of Trolox). However, ABTS has an advantage to the DPPH assay, since ABTS can be used at different...
