The relative density of lead is 11.3. its density `= ….. g cm^(-3) = …….kg m^(-3)`. Fill in the blanks.

Options

A. `1.13xx10^(3)`
B. `1.13xx10^(2)`
C. `1.13xx10^(4)`
D. `11.3`

Answer

C

Explanation

Relative density `=("Density of a substance")/("Density of water")`
`therefore`Density of lead `=11.3xx1xx10^(3)kgm^(-3)`
(`because`Density of water `=1xx10^(3)" kg "m^(-3)`)
`=11.3xx10^(3)" kg "m^(3)=1.13xx10^(4)kg" "m^(-3)`
