Concentration terms (Mole Fraction, Mass Fraction, Molarity, Molality and Normaility)

The concentration of solutions can be expressed in number of ways such that Normality, Molarity, Molality, Mole fractions, Strength, % by weight, % by volume and % by strength. The molarity of ionic compound is usually expressed as formality beacuse we use formula weight of ionic compound. Addition of water to a solution changes all these terms, however increase in temperature does not change molality, mole fraction and % by weight terms. Number of oxalate ions in 100 mL of 0.1N oxalic acis is:

The molarity of ionic compound is usually expressed as formality beacuse we use formula weight of ionic compound. Addition of water to a solution changes all these terms, however increase in temperature does not change molality, mole fraction and % by weight terms. Molecular weight of O_(3) in the reaction, 2O_(3)hArr3O_(2) is:

The molarity of ionic compound is usually expressed as formality beacuse we use formula weight of ionic compound. Addition of water to a solution changes all these terms, however increase in temperature does not change molality, mole fraction and % by weight terms. Which is not a molecular formula?

In which of the following expression the concentration of the solution remains independent of temperature :- Molarity Normality Mole fraction Percentage strength (w/v)

Concentration terms such as mass percentage, ppm, mole fraciton and molality are independent of temperature, however molarity is a function of temperature. Explain.
