Answer is: you can calculate the number of moles of water in a hydrate if you know the empirical formula
of the anhydride.
First measure mass of hydrate, after you heat hydrate, put sample of the compound on scale and measure the mass loss. The
lost mass is water. Now calculate the number of moles
of water and if the ratio is same as empirical formula, all water is lost.
Answer : true
explanation:
Answer:
V is proportional to StartFraction n over p EndFraction.
Explanation:
Let us remind ourselves of the statements of both Boyle's law and Avogadro's laws.
Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Avogadro's law states that at the same temperature and pressure, equal volumes of gases contain equal number of molecules.
Hence ;
V α 1/P (Boyle's law)
V α n (Avogadro's law)
V α n/p (combination of Boyle's law and Avogadro's law)
