Volume of the peat moss =
=
Convert the above volume into
Thus, volume in is:
Volume of peat moss =
=
Now,
Total volume by using area and depth of the peat moss =
=
=
Convert above values in to get the value of volume in
:
Thus, volume in is:
Total volume =
=
=
Now, number of bags is calculated by the ratio of total volume of the peat moss to the volume of the peat moss.
Substitute the values of volume in above formula:
=
≅ bags
Thus, number of bags of peat moss are needed to cover an area measure by
to a depth of
are
bags.
Answer:
14 is this value for a molecule of .
Explanation:
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
Number of total outer valence electrons is carbon = 4
Number of total outer valence electrons is hydrogen = 1
Number of total outer valence electrons is chlorine = 7
For total number of outer electrons is
