What is the force of gravity on a bag of sugar on earth?

The magnitude of that force is printed on the front of every bag of sugar.

Look at it carefully, and you'll find markings like "1 lb" or "5 lb" or "10 lb".

That's code for the gravitational force exerted on that bag when it's full.

Unless your family prefers metric sugar. Then it gets a little more complicated,

because they use mass instead of weight (which is a type of force). To get

the force, multiply the mass printed on the bag in kg by about 9.8 m/s/s.

The answer will be in newtons, which unlike grams and kilograms are

force units.
