Answer to Question #296873 in Inorganic Chemistry for Ninz

Question

the world’s largest gold bar in the toi gold museum in japan can be seen and touched by visitors. it has an irregular shape with dimensions about 17.9 in. by 8.9 in. by 6.7 inches, with a volume of 12.94 l. determine the mass and weight (1 kg = 2.205 lb).

Answer 1

Volume of the Gold bar is given as 12.94 LITRES= 12940cm³

Density of Gold$=19.32g/cm^3$

$\rho=\frac{m}{v}$

$m= 19.32×\frac{12940}{1000}=250kg$

$W=mg$

$Weight = 250× 9.81=2452.5N$
