Answer:

We know that the mass of one papper clip is 1 gram.

now, on the other side of the balance there is a cube centimeter of aluminium, that has a mass of 2.7 grams.

Then, if we want that the mass is equal in both sides, we must have:

X*1g = 2.7g

X=2.7g/1g = 2.7

So we need 2.7 paper clips, rounded to the next whole number, 3 papper clips.
