The molar mass for PCL3 is 137.33 g/mol
Explanation:
Formula to calculate the atomic packing factor is as follows.
APF =
=
It is given that atomic radius is 0.123 nm and density of metal is 7.45 .
Hence, number of atoms will be calculated as follows.
No. of atoms = = 4
APF =
= 1.3905
Thus, we can conclude that atomic packing factor if the unit cell has a tetragonal symmetry is 1.3905.
I think that the answer might be A) 1.5 L of NH3(g)
They are reactants. Reactants combined together in a chemical reaction to form products.
Answer: The atomic number indicates the number of protons within the core of an atom. The atomic number is an important concept of chemistry and quantum mechanics. An element and its place within the periodic table are derived from this concept. ... These electrons mainly determine the chemical behaviour of an atom. The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!! :D
