A spring is attached to a mass, and gravity is pulling it down. Then what is the force that keep the mass up from the floor? Air? Spring, or?
-
Gravity pulls down and the spring resists the force.

The spring is holding it up.
The force exerted by a spring is F=kx (k is the spring constant, and x is the distance the spring is compressed or stretched beyond its resting position).
If it is stationary, then the force of the spring will equal the force of gravity (mg=kx).
