~3.77 m/s²

Explanation:

We can use the equation for finding the acceleration due to gravity on a planet:

We are given the mass of the planet, 6.42 * 10^23 kg, and the radius of the planet, 3370 km.

Let's first convert the radius of the planet to m:

Now, we can plug all of these variables into the equation and solve for g, the acceleration due to gravity on this planet; which, in this case, is Mars.

The acceleration due to gravity on Mars is about 3.77 m/s².
