you should probably be feeding your horse grain instead of liquids
The weight of rice can depend on the specific type of rice grain. For example, a cup of uncooked long-grain white rice can weigh about 150 grams, and a cup of raw long-grain brown rice can weigh 165 grams.
It would depend on what type of grain. But it would probably be somewhere in the range of 7 to 10 lbs.
how much does a gallon of concrete weigh
Weigh an empty container; pour a gallon of water into it. Weigh it again. Calculate the difference. That is the weight of the gallon of water.
Depends how big the grain of salt is.

1 gallon
The weight of a specified volume of liquid depends on the specific gravity of the liquid. This in turn depends on the amount of acetic acid and any dissolved solids in the vinegar, so insufficient data has been provided to answer the question. Roughly, however, 10.1 pounds (the same as water) since normal vinegar is around 5% acetic acid it calculates to 10.1 lb/gal (10lb 1.6oz)
1 US gallon would weigh approx 39.8 newtons.
