Weekend Challenge Math

I made up this little balance problem and put it up on the whiteboard for students to mess around with after finishing their quiz. A couple of students asked if I'd post it.

The idea is that the total weight is 96 grams. The problem works as a mobile, such that both side of the balance are equal, meaning 48 grams on each side. The weights of all of the shapes are whole numbers. See if you can figure out the weight of each type of shape.
