If an object's weight on Earth is 75 N, what is its mass? How do I solve this problem. I must convert Newtons to mass?

Newtons don't "convert" to mass. Newtons are a unit of weight or force. Mass is "how much" stuff there is in an object.
Think of it this way. A 1 kilgram hammer can rest on a table, and will press down on the table with a force of 9.807 N. Or, you can pick it up, and hit the table with a force of 100 N. It's still the same mass, but the force is different.
That said, an object of 1 kilogram will rest on the Earth with a weight of 9.807 newtons (about, the exact number depends on where in the world you are.)
Divide the value in Newtons by 9.8 to get the mass in kg.
F = mg
where F = Weight in newtons
m = mass in kg
g = acceleration due to gravity, 9.8 m/s^2
For 75 N , the mass is 7.65 kg
