Hence,active mass of 5 gram CaOis 1.Active mass of 5 g CaOis 1 because it's a solid.Active massdepends on no of moles of substance per unit volume of a substance. For solids and liquids,active massis always 1 because their density always remains constant.

Active mass depends on no of moles of substance per unit volume of a substance.It's an intensive property.For solids and liquids, active mass is always 1 because their density always remains constant.For gases, active mass changes with change in density.

Active mass of 5 g CaO is 1 because it's a solid.

Active mass of a solid or a liquid is supposed to remain ... The active mass of CaO is 1 gram because it is always equal...

Active mass of a solid or a liquid is supposed to remain constant because it is an intensive property which means that the the number of molecules per unit of a solid or a liquid remain constant keeping in mind that their density is also constant. The molecular weight of solids and liquids unlike gases also remains constant.

The active mass of CaO is 1 gram because it is always equal to 1 in solids.

active mass of 5g CaO is 1 'cuz it's a solid
