To convert parts per million (ppm) to molecules per cubic centimeter, you need to know the molecular weight of the substance. Use Avogadro's number (6.022 x 10^23) and the formula: molecules/cm^3 = (ppm * density * 6.022 x 10^23) / (molecular weight * 10^6). This will give you the concentration of molecules per cubic centimeter.
