Firstly, Kg is a unit for mass while Litre is a unit for volume. So there is actually no relation. They are only related by density= mass/volume or volume=mass/density.
mass=density * volume, and volume=mass/density. Though if you want you can take 1 litre as 1kg. So you can substitute values and do it :)
