Elemental phosphorus can be prepared from calcium phosphate via the overall reaction 2 ca3(po4)2 1 6 sio2 1 10 c 8n 6 casio3 1 p4 1 10 co calculate the minimum mass of ca3(po4)2 required to produce 69.8 g p4. what mass of casio3 is generated as a by-product?

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.
