For an object that is not moving or moving at a constant speed (in any direction), the sum of the forces (in any direction) must sum up to zero. You can use this information to solve for the normal force acting on an object.
Newton's First Law Application
\(\large\mathsf{ \Sigma F = \overrightarrow{F}_{normal} + \overrightarrow{F}_{weight} = 0 }\)
Using what you know, match the mass of the object with the normal force acting on the object, assuming that the object is sitting on a solid surface and not moving.
