Depends on the hose, obviously different hoses weight different amounts.
It is an accepted fire service understanding that 5" Large Diameter Hose (LDH) will hold 1 gallon/ft. On average a 100' section of 5" empty weighs 110 lbs. With water weighing 8.33 lbs/gal. a 100' section of LDH filled with water will weigh approximately 944 lbs.
Pre-1982 Lincoln cents weigh 3.11 grams and have a diameter of 19mm, 1982 to date weigh 2.5 grams with the same diameter.

it is the same weigh.
Weigh it (weight of container including water) minus weight of empty container. A length (cm) is not a suitable unit for measuring a quantity of water without more information.

That section of hose holds 25.5 gallons of water when it's full, which weighs about 213 pounds. To that, add the weight of the empty hose, which I don't know.
25 pounds
That would depend on the temperature and is this fresh or sea water? About 305.72
This cylinder holds up to 0.154 liter of water.
0.5 pounds
it will probably settle down when you weigh it down with more water
use the water displacement method
Less, ovbiously.

Assuming the hose has an inner diameter of 1 inch, 100 feet of 3" hose filled with water would weigh approximately 6,242 pounds.
