Question

Rohan got a gold chain made from a cuboidal black of gold.How can he find the purity of the gold by using the density of pure gold?​

Answer 1

Answer:

Divide the mass of the object with its volume to yield the density of the object

for example:the object density = mass/ volume

Now compare the density to that of the pure gold (19.3 g/cc)

and now you can determine whether the gold is pure are not

I hope it helps you

Mark it is a brainliast answer.

Answer 2

Answer:

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
