As per the formula of weight, Arnold's mass is 73.5 kg.

What is the weight of an object?

The weight of an object is the product of it's mass and the acceleration due to gravity.

Given, Arnold's weight is 721 N.

The acceleration due to gravity is 9.81 m/s²

We know, weight = mass × acceleration due to gravity

⇒ Mass = weight/ acceleration due to gravity

⇒ Mass = 721/9.81

⇒ Mass = 73.5
