B. The third shell would be empty so that the eight electrons in the second level would be outermost after the atom loses one electron.
Mass of the substance = 360 gm
Volume of the substance = 7.5 cm^3
Now we know that
Density = Mass/Volume
= 360/7.5 gm/cm^3
= 48 gm/cm^3
So the density of the substance given in the question is 48 gm/cm^3.
. I hope that you have
understood the procedure by which the density of any substance can be easily
determined and also got the answer you were looking for. By following this
method you can easily determine the density of any substance without requiring
any help.
Answer:
cutting, bending, dissolving, freezing, and boiling
