A40-lb container of peat moss measure 14x20x30 inches and has an average density of 0.13 g/cm^3. how many bags of peat moss are needed to cover an area measure 1 3ft by 25 ft to a depth of 1.9 inches?

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.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

answer: h+ its less than oh
