How much does a water bottle cap weigh in grams?

Answer 1

If the bottle holds 500 mL of water, then its contents have a nominal mass

of 500 grams, and weigh 4.9 newtons (1.1 pounds) on Earth.

-- If it holds some other substance, then its mass and weight are different.

-- If it is weighed in some other place, then the weight of the same mass is different.

-- This discussion applies only to the bottle's contents. We have no way to estimate

the mass or weight of the container.
