volume of substance = 50/1000000 x 15000 = 0.75 liters = 750 cubic centimeters
mass = specific gravity x volume = 1.31 x 750 = 982.5 grams
15000L
This cannot be sensibly answered. A litre is a measure of volume, kg is a measure of weight or mass.
In my case, the little rope went off and i was trying to fix it again.I just did it and it was easy and I just did it. See the steps:1) In back part of the cover i used a Screwdriver to puch the white part that holds everyhting together. Then, everything is easy too figure out.2) Then I used a Crosshead screwdriver to take 3 screws (bolts) our to open the final mechanism.3) Then I used a silicon glu to stick the rope at the round mechanism. Be aware to fix the rope in a way it does not get to loose.4) Make a try. If it is loose, just detach the rope try fix it again.5) Once It`s working properly, just put every part back again and made a final test.
