Question

Calculate the number of CO2 molecules in 0.0334 molmol of CO2.

Answer 1

This uses the formula :

(# of atoms/moluecules = mol * Avogadro's constant)

6.022*10^-23 is Avogadro's number which is the number atoms that are in a mol of atoms. So 1 mol has exactly 6.022*10^-23 atoms.

Therefore:

$0.0334*(6.022*10^{-23}) = 2.01135*10^{-24}$
