Answer 2

 An experiment to determine the density of the material of the coin has a basic requirement of knowing the material used in the coin. The density of a coin can be known easily by measuring the weight of the coin in the air and the weight of the coin displaced by the amount of water. Density is the ratio of mass to the volume.

  Therefore, measure the weight of the coin in the air by a precision scale as M. Get a beaker full of water and weigh it. now place the coin inside the water without touching any side of the beaker and weigh the displaced weight as V.

Now find out the ratio between the two and that will be the density of the material of the coin.

Density $=\frac { M }{ V }$.
