Question

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

Answer 1

Answer : The Molar mass of the compound Di-nitrogen peroxide i.e  $N_{2}O_{5}$  = 108.02 g/mol

Solution :

Molar mass of $N_{2}O_{5}$ ,

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 $N_{2}O_{5}$.

              Molar mass of $N_{2}O_{5}$ =  $2\times (N) + 5\times (O)$

                                                =  $2\times (14.01) + 5\times (16.00)$

                                                                          = 108.02 g/mol
