standard solutionone that contains in each liter a definitely stated amount of reagent; usually expressed in terms of normality (equivalent weights of solute per liter of solution) or molarity (moles of solute per liter of solution). supersaturated solutionan unstable solution containing more of the...
For the reaction:aA + bB <=> dD + eEKp = ((PD)d(PE)e) / ((PA)a(PB)) They can be interconverted using the ideal gas equation and our definition of molarity:PV = nRT thus P = (n/V)RTIf we express volume in liters the quantity (n/V) is equivalent to molarity.Thus the ...
