find the active mass of nacl.
help me​

Answer 1

Answer:

the active mass of  NaCl (solid) is 1

Explanation:

Given

moles of NaCl = 2 mol

Volume = 4 L

Solution

The active mass of pure liquids or solids is a constant quantity that is unity. this is due to the fact that it is an intensive property "number of molecules present per unit volume do not change" because molecular weight and density of  pure liquids and solids are constant.

As NaCl is a solid, therefore, the active mass of  NaCl (solid) is 1.
