The volume of a gas is defined by the volume of its container.  

However, given the number of moles, and standard temperature and pressure, you can use the Ideal Gas Law to calculate the volume.

Why is it not correct/precise to say "a molecule of salt?"
Fynjy0 [20]

It is not correct to say " a molecule of salt " because salt is a compound.

Explanation:

  • As we know a molecular bond is present in each molecule.
  • Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
  • On the other hand it is not considered as a molecule as it is not holding an ionic bond.
  • As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.

A 0.300 m solution of hcl is prepared by adding some 1.50 m hcl to a 500 ml volumetric flask and diluting to the mark with deion
liberstina [14]
In dilution we add distilled water to decrease the concentration of required sample from high concentration to lower concentration
The law used for dilution:
M₁V₁]Before dilution = M₂V₂] After dilution
M₁ = 1.5 M
V₁ = ?
M₂ = 0.3 M
V₂ = 500 ml
1.5 * V₁ = 0.3 * 500 ml
so V₁ = 100 ml and it completed to 500 ml using 400 ml deionized water
