Answer is: 4) both the rate of dissolving and the rate of crystallization are equal and greater than zero.
Silver chloride (AgCl) dissolves and form silver and chlorine ions, in the same time silver and chlorine ions crystallizate and form solid salt silver chloride.
In equilibrium rates of dissolvinf and crysallization and concentration of ions do not change.
1- mole of any Substance will have the same number of Molecules.
Molecular weight of CO2= 44
Molecular weight of H20= 18
So 18 g of H20 will contain the same Number of molecules as in 44 g of CO2.
Therefore 7.2 g of H2O will have same Number of Moleculesas in =7.2/18 x 44
= 17.6 g of CO2.
