Liquids have fixed volume but not fixed shape, so B.
Molecular structure. Isomers have the same formula, so there is the same elements in both. But they have a different molecular structure and when drawn they look different
Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:
10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
