Use the periodic table from the lesson to answer the following question. the atomic mass of f is 9 10 19 55

In this case if given those choices your answer would be (C. 19).

However in more complicated Chemistry rules you would learn that the periodic table only showcases 1 of the many possible masses of the element.

Hope this help! :D  

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
