How many molecules are in

3C2H3O

Here we have to get the number of molecules present in 3C₂H₃O

There are 1.806*10²⁴ number of molecules in 3C₂H₃O

As per Avogadro there are 6.023*10²³ number of molecules are present in per mole of a compound.

In this compound there are 3 moles of the compound thus total number of molecules will be 3*6.023*10²³ = 1.806*10²⁴.

Thus the number of molecules present in 3 moles of C₂H₃O compound is determined.
