To find the weight of the desk, we need to use the formula that relates mass and weight. The weight \(\( W \)\) of an object is given by the formula:
\(\[ W = m \cdot g \]\)
where:
- \(\( m \)\) is the mass of the object (in kilograms).
- \(\( g \)\) is the acceleration due to gravity (approximately \(\( 9.8 \, \text{m/s}^2 \)\) on the surface of the Earth).
Given:
- The mass \(\( m \)\) of the desk is \(\( 80.0 \, \text{kg} \)\).
Now, we will calculate the weight:
\(\[ W = 80.0 \, \text{kg} \times 9.8 \, \text{m/s}^2 \]\)
\(\[ W = 784 \, \text{N} \]\)
So, the weight of the desk is \(\( 784 \, \text{N} \)\).
Thus, the correct answer is:
\(\[ \text{784 N} \]\)
