Molar example sentences

This is applicable even to soluble salts like sodium chloride except that due to higher concentrations of the ions, we use their activities instead of their molarities in the expression for Qsp.The standard enthalpy change for the formation of one mole of a compound from its elements in their most stable states of aggregation (also known as reference states) is called Standard Molar Enthalpy of Formation.HL primarily helps to maintain osmolar gradient (300 mOsmolL–1 -1200 mOsmolL–1) within the kidney interstitium.We can simplify equilibrium expressions for the heterogeneous equilibria involving a pure liquid or a pure solid, as the molar concentration of a pure solid or liquid is constant (i.e., independent of the amount present).Let [CO], [H2], [CH4] and [H2O] be the molar concentrations at equilibrium for methanation reaction.Molar concentration of different species is indicated by enclosing these in square bracket and, as mentioned above, it is implied that these are equilibrium concentrations.The reaction quotient, Q (Qc with molar concentrations and QP with partial pressures) is defined in the same way as the equilibrium constant Kc except that the concentrations in Qc are not necessarily equilibrium values.This results in units of equilibrium constant based on molarity or pressure, unless the exponents of both the numerator and denominator are same.This segment allows passage of small amounts of urea into the medullary interstitium to keep up the osmolarity.An adult human has 32 permanent teeth which are of four different types (Heterodont dentition), namely, incisors (I), canine (C), premolars (PM) and molars (M).It is important to understand that a standard molar enthalpy of formation, ?fH0, is just a special case of ?rH0, where one mole of a compound is formed from its constituent elements, as in the above three equations, where 1 mol of each, water, methane and ethanol is formed.However, this region plays a significant role in the maintenance of high osmolarity of medullary interstitial fluid.Standard state (c0) for a solute is 1 molar solution and all concentrations can be measured with respect to it.Their melting point, boiling point and density increase with increase in molar mass.So far we have expressed equilibrium constant of the reactions in terms of molar concentration of the reactants and products, and used symbol, Kc for it.
