Answer:
60 ml
Explanation:
Now, we know that density = mass/volume
Mass of aluminium = 67.5 g
volume of aluminium =?
density of aluminium = 2.70 g/mL
volume of aluminium = mass/density = 67.5/2.70 = 25 ml
Since volume of water in the cylinder = 35 ml
The water rises to ; 35 ml + 25 ml = 60 ml
For an element whose third shell contains six electrons, the appropriate electron configuration is; 1s2 2s2 2p6 3s2 3p4.
The electron configuration shows the distribution of electrons in the shells of an atom and in orbitals.
We have been told that the six electrons are found in the third shell. This shell has n=3 and the configuration of this shell must ns2 np4.
The only electron configuration that meets this standard is 1s2 2s2 2p6 3s2 3p4.
