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* (N) + 5* (O)`

=
`2* (14.01) + 5* (16.00)`

= 108.02 g/mol
