A scalar quantity is a quantity that includes both magnitude (the number) and a unit, but not direction.
An example of this is 5m.
C , the potential energy of a 500kg boulder
Answer: 587.971086 ≈ 587.97
Explanation: one gram in moles of H3PO4 is 97.995181 so if you just have to multiply it by 6 to get the answer. I could be wrong.
Gases can be compressed easily because there is a large amount of space between the individual molecules, which are very active and move around at high speed. When gases are compressed, the particles are forced much closer together, allowing a huge amount of particles to fit a small space.
