it depends on the size

how much would a water balloon 19 cm by 6 cm weigh
10g
Water is very good at soaking up heat. When the water-filled balloon is heated the water Draws the heat away from the rubber. For the air filled balloon, not so much. The rubber heats up, weakens, and breaks.
A 1L pitcher of water will weigh exactly 1kg.
1 litre of water = 1 kg
I interpret this question to be asking how one might measure the volume of a water balloon without breaking the balloon or emptying it of the water in order to measure its volume. One method is to fill a container with water that will be large enough to contain the water balloon, and then submerging the water balloon in the container. The volume of the balloon will be the apparent volume change of the water in the container. Any measurement will introduce some error. Since water compresses hardly at all, one would expect that submerging the balloon would not significantly change the volume of the balloon. There could be some error if one had to push down on the balloon to make it fully submerge. There will also be some measurement error in determining the volume change.
8 pounds
About 67 ounces
456 pounds
If 1 water balloon weighs 5 ounces, 8 water balloons would weigh 40 ounces, which is two and a half pounds.
The exact same weight as when you put it in..... 2 pints of water weighs about 1.2kg

The weight of a hot-air balloon can vary depending on its size and design. On average, a small hot-air balloon can weigh around 250-400 pounds (113-181 kilograms), while larger ones can weigh over 1,000 pounds (453 kilograms) or more.
which water?
how big is the ballon?
It can hold up to, 8 to 17oz. It matters how big your balloon is.
no
Probably the simplest way would be to fill a container having a known volume (say, a 5 gallon bucket) with water right to the top, weigh it, then push the balloon under the water. The water displaced by the balloon will spill out. (Your hand will displace water too, which screws things up, so use something like a stick to push the balloon all the way in.) Now take the balloon out of the water and weigh the bucket again. The difference between the earlier weight and the final weight is the weight of the water that the balloon displaced. The density of water is 1 gram per cubic centimeter (cc), so (to a very good approximation) the volume of air in your balloon in cc is the same as the weight of the displaced water in grams.
