Hard to say with wood in this chipped state, and no end grain visible. And no idea of the guitar model.
The only clue would be the color : if that's the body, possibly alder? Might be maple too, but less likely. If it's a crappy body, balsa, but that would weight almost nothing.
Persimmon, aka white ebony ?
All far fetched attempts, only my 2 cents.
