The answer that best fits the blank provided above is MECHANICAL.
Weigh everything at once (water and container) get that number.
empty the water into a bowl or container
weigh the original container that the water was in previously
subtract (total weight) - (container weight)
The a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.
What is pressure gauge?
A device used to measure a fluid's (liquid or gas') state by calculating the force the fluid would apply to a unit area if it were at rest.
What is pressure?
The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables.
Therefore, a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.

Answer:
molecules present in, 76 gram of fluorine
Explanation:
atomic weight of fluorine is 19 g per mole, molecular weight is 38g per mole .
Therefore 76 gram fluorine contains 1976=4 gram atom
The element X is Copper.
Explanation :
Reactive metals from 3d transition series like Cu are very reactive because their standard reduction potential values are low.
Hence, when treated with a acid it tends to liberate hydrogen gas.
Also, because of its low reduction potential value, it can easily displace lead and tin from their salt solutions.
