A constant force of 9.8N is applied to a wooden block to slide it at a constant speed across a wooden table. Determine the weight of the block.
What is the mass of the block?

You have not provided enough information t answer the question. I assume the table is level. The friction force equals 9.8N so that the no accleration occrs.
Therefore
(Weight)*(kinetic friction coefficient)
= 9.8 N
The kinetic friction coefficient is needed to calculate the weight. You may have been told what it is but you neglected to include it in your question
The mass of the block is (Weight, in newtons) divided by g.
