"the same";
One mole of any given thing is 6 * 10²³ of it;
One mole of H₂O is 6 * 10²³ molecules;
One mole of O₂ is also 6 * 10²³ molecules;
Therefore for both substances, there are the same number of molecules.
Basic copper carbonate is decomposed by acids, such as solutions of hydrochloric acid HCl, into the copper(II) salt and carbon dioxide. In 1794 the French chemist Joseph Louis Proust (1754–1826) thermally decomposed copper carbonate to CO2and CuO, cupric oxide.

To convert 390 ml to grams, besides the volume we have to know the substance’s density ρ in g/cm3<span> or in any other unit. Alternatively, when we know the material, then we can look for its density in a search engine. As explained on our home page, 390 ml equal 390 cm</span>3<span>, and as also outlined there, in common use the equation for water is 390 milliliter = 390 g</span>
