75 ml L

It seems like there may be a typo in your question, as "75 ml L" doesn't make sense in standard units of measurement. Milliliters (ml) and liters (L) are both units of volume, with 1 liter being equal to 1000 milliliters. It's possible that you meant to ask about converting 75 milliliters to liters, in which case the answer would be 0.075 liters. If you have a different question or need further clarification, please provide more context.
