This would be the molar mass.
Mhm, it keeps the planets in place and circle around the Sun's gravitational pull, like how the Earth's small-like gravitational pull keeps the moon to circle around our planet, and as a perk it makes the 80% water that around this whole place to have high and low tides.

Answer:
The correct answer is option false.
Explanation:
Molality of the solution defined as moles of substance present in 1 kilogram of solvent.
Moles = 

Mass of percent (w/w%) of the solution is defined as amount of solute present in 100 grams of solution.

So, if want to inter-convert molality into mass percent we can do that without knowing density of solution.
Mass of solution = Mass of solute + Mass of solvent
Answer:
Heat energy.
Explanation:
The exited electron releases the absorbed energy as heat energy that provides energy to electrons to move from one orbit to another orbit. The electron avails kinetic energy which provides motion in the electron when the energy is absorbed by the electron while on the other hand, electron releases energy which brings the electron into its original orbit. So we can say that the electrons releases energy in the form of heat and come back to its original place.
