Answer:
By definition, there are 6.022×1023 such molecules, or NA such molecules in ONE mole of water. And thus in such a quantity there are NA oxygen atoms, and 2×NA hydrogen atoms...and the mass associated with this numerical quantity of water molecules is approx. 18⋅g ...
PH indicators detect the presence of H+ and OH-. They do this by reacting with H+ and OH-: they are themselves weak acids and bases. If an indicator is a weak acid and is coloured and its conjugate base has a different colour, deprotonation causes a colour change.
Carbonic acid refers to a weak inorganic acid, which is also known as the solution of carbon dioxide in water. It only prevails as a solution and is also known as the aerial acid, acid of air, dihydrogen carbonate, or carbon dioxide solution. It is most familiar as a constituent of the majority of the aerated drinks like soft drinks and sodas.
The carbonic acid's chemical formula is H₂CO₃. Its decomposition to water and carbon dioxide is shown by the equation:
H₂CO₃ (g) = H₂O (l) + CO₂ (g)

<span>In order convert the mass of a substance to its number of moles The conversion factor is the reciprocal of the molecular weight of the substance. Hence, for the given element in the problem- potassium, the equivalence factor is d. </span><span>(1 mol K/39.10 g K). </span>
