What would the mass of a dog be if it has weight 100?

You can't determine the dog's mass with just the weight being 100. Here's why:

* Weight vs. Mass: Weight is the force of gravity acting on an object's mass. Mass is the amount of matter in an object.

* Units: We need to know the units of the weight.

* If the weight is 100 Newtons (N), then we can calculate the mass.

* If the weight is 100 pounds (lbs) or 100 kilograms (kg), we can't directly convert it to mass because those units represent force.

To find the mass, we need to know the weight in Newtons (N) and then use the following formula:

* Weight (N) = Mass (kg) * Acceleration due to gravity (m/s²)

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Example:

If the dog's weight is 100 Newtons, we can calculate its mass:

* 100 N = Mass * 9.8 m/s²

* Mass = 100 N / 9.8 m/s²

* Mass ≈ 10.2 kg
