Q) A gold colored ring has a mass of 18.9gms and a volume of 1.12mL .Is the ring pure gold ?(The denisty of gold is 19.3g/mL)

The ring is not made of pure gold as the density of gold is 19.3gm /mL but we are getting 16.875gm/mL

Use the formula Density = mass / volume

D= M/V

M= 18.9 gm  , V=1.12 mL, D= 19.3gm/ mL

But If we divide mass / voulme 

M / V = 18.9 / 1.12 = 16.875gm /mL

So the ring is not made of pure gold as the density of gold is 19.3gm /mL
