Alead atom has a mass of 3.14 x 10 to the negative 22nd g. how
many lead atoms are in a cube of lead that has a volume of 2.00cm
cubed, if the density of lead is 11.3 g/cm cubed?

Explanation:

The given data is as follows.

       Mass of a lead atom =

       Volume = 2.00

        Density = 11.3

As it is mentioned that 1 cubic centimeter contains 11.3 grams of lead.

So, in 2 cubic centimeter there will be of lead atoms.

One lead atom has a mass of . Therefore, number of atoms present in 22.6 g of lead will be as follows.

                  =

Thus, we can conclude that there are of lead are present.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
