diagram for demo

Archimedes' principle: Weighing glassware and water. A beaker rests on a scale that has been tared. An empty glass vessel is held by a clamp and suspended inside the beaker, but does not touch it. Water is added to the beaker until it reaches the 500ml mark. What does the scale measure when the water has been added?
