A lab group wishes to determine the volume of some zinc beads. They fill a graduated cylinder to the 42.55-mL mark with water. They carefully add the beads to the cylinder. The water level rises to 76.85 mL. What value should they report as the volume of the zinc beads? ​

The value the group should report as the volume of the zinc beads will be 34.30 mL

Volume of solids by sinking method

The volume of a regular solid can be determined by allowing the solid to sink or float in a liquid in a calibrated cylinder.

The principle is such that a floating or sinking liquid will always displace its volume in any liquid.

Thus, assuming the initial level of the liquid in a cylinder is 50 mL. If the cylinder reads 70 mL after inserting the solid, the volume of the solid is calculated as the differences between the final and the initial cylinder readings.

In this case; initial reading = 42.55 mL, final reading = 76.85 mL

Volume of zinc beads = 76.85 - 42.55

                          = 34.30 mL
