To convert density from mol/L to kg/m³, first recognize that there are 1000 liters in a cubic meter. The conversion from moles to mass requires knowledge of the substance's molar mass, which varies by material; for example, 1 mole of hydrogen weighs 0.002 kg while 1 mole of plutonium weighs 0.24 kg. The volume of 1 liter in SI units is equivalent to 0.001 m³, as 1 cm³ is equal to 1 mL. Understanding the molar mass in appropriate units, such as kg/kmol, is essential for accurate conversion. Accurate conversion relies on both the volume and the specific molar mass of the substance in question.
