Question

# Relative density of silver is 10.5. The density of silver in SI unit is  _________.

A
10.5×103 kgm3
B
10.5×103 gcm3
C
20.5×103 kgm3
D
20.5×103 gcm3

Solution

## The correct option is A 10.5×103 kgm−3Given: Relative density of silver, ρs,w=10.5 Density of water is ρw=1000 kgm−3 Let the density of silver be ρs From definition of relative density: ρs,w=ρsρw ρs=ρs,wρw ρs=10.5×103 kgm−3
