We’re being asked to determine the total number of atoms in a sample of cocaine hydrochloride, C17H22ClNO4 of mass 23.0 mg.
We can calculate the total number of atoms using the following steps:
Step 1: Convert the mass from mg to g.
Step 2: Convert the mass to moles (using molar mass).
Step 3: Convert the moles to # of molecules (using the Avogadro’s number)
Step 4: Convert the # of molecules to number atoms to moles (from the molecular formula)
mass C17H22ClNO4 (molar mass) → moles C17H22ClNO4 (Avogadro’s number) → molecules C17H22ClNO4 (# of atoms per molecule) → total # of atoms
Find the total number of atoms in a sample of cocaine hydrochloride, C17 H22 ClNO4, of mass 23.0 mg .
