Thank you for your videos!!! Can you tell me why you had to convert to ml and not let it as mL?

[Papapodcasts]

@Alysassy You are very welcome. The reason for changing the units is because, in order to calculate the m/v% units have to be in mL and cannot remain as L, otherwise it would have higher percentages and give a false sense of ratio between the mass and volume. Hope that helps. Good luck with your studies.
