An advanced light microscope has a limit of resolution of 0.3 μm0.3\text{ }\mu\text{m}0.3 μm (micrometres). A state-of-the-art cryo-electron microscope has a limit of resolution of 120 pm120\text{ pm}120 pm (picometres). How many times greater is the resolution of the cryo-electron microscope than that of the advanced light microscope? (Given that 1 micrometre (μm)=1,000,000 picometres (pm)1\text{ micrometre } (\mu\text{m}) = 1,000,000\text{ picometres } (\text{pm})1 micrometre (μm)=1,000,000 picometres (pm))
