By carrying out the water displacement method
A CORK stopper is a plug for a bottle made of cork
The volume of a rubber stopper can vary depending on its size and shape. To find the volume of a rubber stopper, you can use the formula for the volume of a cylinder or sphere, depending on the shape of the stopper. Measure the dimensions of the stopper and plug them into the appropriate formula to calculate the volume.
You really can't use the same cork. You would have to purchase a champagne cork stopper. It's a cork stopper that has a clamp on it.

Cork
You can find the volume of the irregular cork by immersing it in a known volume of water and measuring the amount the water level rises. The volume of water displaced is equal to the volume of the cork.
a cork regards ´LG
Yes it does. If you go to Google andtype in "The Ashes Urn" and go into images there will be a picture and the stopper is clearly made out of cork.
It?æ is hard to find the density of a cork in water because?æ cork floats?æ in water. Density of a substance is given by its?æ mass divide?æ by its volume and since cork does not submerge, it is difficult to find its volume.
Cork is a natural material obtained from a particular species of tree.
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.
Its reduces evaporation, and something else i dont know! :)
