Gold biscults are available in the market which look exactiy similar to gold but actually they are not of pure gold (but of gold called fool's gold). How will check it by some simple physical property? Density of pure gold is well known to be 19.3 g `cm^(-3)`.

Text Solution

Verified by Experts

We can find out the exact mass and volume* of the given gold bisult and then calculate its density. If it is not made of pure gold, its density will come out to be different from that of pure gold.
