Using Newtons second law of motion if the force on an object is 20N, and its mass is 5g, what is it's acceleration?

now I'm not sure what to do. Can someone please help?

  • physics -

    You need mass in kg

    acceleration in m/s^2 is force in newtons, divided by mass in kilograms.

    Would it be
