To find the weight of the desk, we need to use the formula that relates mass and weight. The weight [tex]\( W \)[/tex] of an object is given by the formula:

[tex]\[ W = m \cdot g \][/tex]

where:
- [tex]\( m \)[/tex] is the mass of the object (in kilograms).
- [tex]\( g \)[/tex] is the acceleration due to gravity (approximately [tex]\( 9.8 \, \text{m/s}^2 \)[/tex] on the surface of the Earth).

Given:
- The mass [tex]\( m \)[/tex] of the desk is [tex]\( 80.0 \, \text{kg} \)[/tex].

Now, we will calculate the weight:

[tex]\[ W = 80.0 \, \text{kg} \times 9.8 \, \text{m/s}^2 \][/tex]
[tex]\[ W = 784 \, \text{N} \][/tex]

So, the weight of the desk is [tex]\( 784 \, \text{N} \)[/tex].

Thus, the correct answer is:
[tex]\[ \text{784 N} \][/tex]
