Give the molecular mass of the compound depicted below and alter the name if it is named incorrectly. dinitride pentaoxide

Answer : The Molar mass of the compound Di-nitrogen peroxide i.e    = 108.02 g/mol

Solution :

Molar mass of ,

Step 1 : Identify the number of atoms of each element in the compound.

            Number of Nitrogen atoms (N) = 2

            Number of Oxygen atoms (O) = 5

Step 2 : Find the atomic mass of each element in the compound.

             Atomic mass of Nitrogen  (N) = 14.01 g/mol

             Atomic mass of Oxygen (O) = 16.00 g/mol

Step 3 : Calculate the Molar mass of the given compound .

              Molar mass of =  

                                                =  

                                                                          = 108.02 g/mol

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
