Question

A. Vishal goes to a jewellery shop with his parents and buys a gold pendant. When he comes back home,
he refers his science book and finds the density of gold to be 19.3 g cm. How can he determine if the
pendant he has bought is made of pure gold?​

Answer 1

changing 19.3g/cm^3 into lg/m^3.

19.3×1000kg/m^3

=19300kg/m^3

SINCE DENSITY OF GOLD IS 19300KG/M^3,IT IS A PURE GOLD LOCKET.
