The formula for force is F=ma. Because weight is a measure of force, then we can substitute the weight of the meteor, 3204 N, for F in the the equation for force. We also know that the acceleration of gravity on Earth is 9.8 m/s^2. To find the mass, simply divide both sides of the equation by the value of acceleration to get
$m = \frac{f}{a} = \frac{3204}{9.8} = 326.9$
Therefore, the value of the mass of the meteor is 326.9 kg.
