Numerical . A jeweller claims that he makes ornaments of pure gold that has a relative density of 19.3. He sells a bangle weighing 25.25 g to a person. The clever customer weighs the bangle when immersed in water and finds that it weighs 23.075 g in water. With the help of suitable calculations, find if the ornament is made of pure gold or not. please help me

Explanation:
loss of weight in water = 25.250 - 23.075
= 2.175gf
loss of weight in water = mass of displaced water
= (volume of displaced water) × (density of water)
= 2.175gf
if we consider density of water
= 1
cc
g
, then,
volume of displaced water = volume of bangle = 2.175 cm
3
mass of bangle,
if it is made by pure gold of relative density 19.3 = 2.175 ×19.3
= 42 gf
Conclusion :-
Bangle is not made by pure gold of relative density 19.3
