The chemical formula of ammonia is written as NH3 we can just use the ratio of the atoms since we are not given the reaction. We also make use the avogadro's number to convert from moles to molecules. We calculate as follows:
5.01 x 10^-4 g H2 ( 1 mol / 2.02 g H2 ) ( 2 mol NH3 / 3 mol H2 ) ( 6.022x10
^23 molecules / 1 mol ) = 9.96 x 10^19 molecules NH3
The atomic number of zinc is 30 therefore The electronic configuration of zinc is expressed as 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 or in simpler form expressed as [Ar] 3d^10 4s^2. The electronic configuration shows the distribution of the electrons of an atom or a molecule.
Answer:
Density is an intensive property
Explanation:
The intensive properties don´t depend on mass or size, if you have a liter of water, this litter have a density equal 1000 kg/m^3. If zo have 250 liters of water, the density is 1000 kg/m^3 too.
The density does not change with the addition or substraction of matter.
I hope I have been clear.
