The density of silver metal bar is 10.5 g/cm3 and it occupies a volume space of 0.5l. what is its mass in kilograms (kg).

Density is equal to the ratio of mass to the volume.

The mathematical expression is given as:

Density of silver metal bar=

Convert into g/L

= 0.001 L

Thus, density  =

=

Volume = 0.5 L

Put the values,

=

Now, convert gram into kg

1 g = 0.001 kg

Therefore, mass in kg=  

= 5.25 kg

Thus, mass of silver metal bar in kg=5.25 kg
