Physics Help... Applying Newtons Laws Grade 11?

On the surface of the earth a geological hammer has a mass of 1500g. Determine its mass and weight on Mars where g=3.6 m/s^2.

The mass stays the same on Mars.

The weight on Mars is M g = 1.5 *3.6 = ___ Newtons

Notice that M must be in kg, not grams, when doing the multiplication.
