8 kg is the weight of the bucket plus a full bucket of water. 4.8 kg is the weight of the bucket plus half a bucket of water.
Subtract #2 from #1 to get
3.2 = w/2
so
6.4 = w
substitute that into #1 to get 1.6 kg for the bucket.
The question is what is the weight with w/4
1.6 kg for the bucket and (4.8)/4 for the water
1.6 + 1.2 = 2.8 kg ■

At 17oC one gallon of water weighs 4.536kg.
This depends on the substance you are measuring. If you are measuring water:1 US gallon weighs 3.78541178 kg1 UK (Imperial) gallon weighs 4.54609118 kg
100 liters of water weighs 100 kilograms, as 1 liter of water is equivalent to 1 kilogram.
One gallon of water weighs approximately 8.34 pounds or 3.78 kilograms.
That really depends on the bucket, but it would be measured kilograms.
8.34 pounds = about 3.8 kilograms.
The weight per US gallon of water at 25 C is 8.33 pounds [per gallon. 2 gallons of water would weigh 16.66 pounds plus the weight of the bucket itself.
70,000 gallons of plain water weighs 3,807.13 kilograms.
A gallon of water weighs about 8.34 pounds. If you have a good sized bucket with a gallon of water in it and you put a 5-pound fish in the bucket, you'll have a bucket that weighs about 13.34 pounds (plus the weight of the bucket). That's as long as the bucket doesn't overflow. The fish will (usually) be neutrally bouyant in the water, and it will be essentially weightless in that water. But its weight will add to that of the water in the bucket. No, it won't weigh 15 pounds, but it will weigh in as suggested. However, the weight of the water itself will not change.
3 liters of water weighs 3000 grams or 3 kilograms
To solve this problem, we need to understand the concept of buoyancy. When the bucket is half-filled with water, the water exerts an upward buoyant force equal to the weight of the water displaced. Since the weight of the half-filled bucket is 30kg, the weight of the water in the bucket is 30kg. This means the weight of the empty bucket is 20kg (50kg - 30kg = 20kg).
If you think only of the liquid pure water then 50 litres of pure water weighs 50 kilograms.
Gallons of what? Different liquids have different weights. A gallon of water weighs 3.7854118 kilograms. A gallon of milk weighs 3.89 kilgrams. A gallon of gasoline weighs 2.835 kilograms. A gallon of ethanol weighs 2.987 kg. A gallon of mercury weighs 51.2165976 kilograms.
