1.505*10^{24}  molecules

Explanation:

The number of molecules is independent of the subtance, and only depends on the number of moles.

To calculate the number of molecules in a substance with n moles you use the following formula:

m: number of molecules

NA: Avogadro's number = 6.02*10^23 molecules/mol

n: moles of the substance = 2.5 mol

You replace the values of n and NA in the equation for m and you obtain:

hence, the number of molecules is 1.505*10^24

3.2x10^7
