Step-by-step explanation:

The number of moles of a substance is represented by the following formula:

n=NNA

where, n

is the number of moles of the substance, N

is the total number of molecules present in a substance, andNA

is the Avogadro constant.

The given compound is N2O5

So one mole of N2O5

contains 6.023×1023

numbers of molecules. Thus the 0.400

moles of N2O5

contains a number of molecules => 0.400moles×6.023×10^23

.

=> 2.41×10^23 molecules.
