Having a bleat

It depends on which 150, they seem to vary from 440kg all the way to over 500.150E

The 1965 Cessna 150E saw only the addition of new seats, although the standard empty weight went up 40 lb (18 kg) that year to 1,010 lb (460 kg). The "E" model saw production increase to 1637 aircraft.[6]

It also seems to depend on whose account you read. I doubt there are too many below much below 500kgs.
