A chemist wants to measure the volume of an irregular specimen of lithium metal using a displacement can filled with mineral oil.
The density of the lithium is 0.53 g/cm3.
The density of the mineral oil is 0.85 g/cm3.
Explain why this displacement method cannot be directly used to determine the volume of this specimen of lithium.
