The relative density of lead is 11.3. Its density in SI unit is

A

1.13 × 103

B

1.13 × 102

C

1.13 × 104

D

11.3

Answer

1.13 × 104

Explanation

Solution

Relative density Relative density

=Densityofasubstan⁡ceDensityofwater= \frac{Densityofasubs\tan ce}{Densityofwater}

∴\thereforeDensity of lead = 11.3×1×103kgm−311.3 \times 1 \times 10^{3}kgm^{- 3}

= 11.3×103kgm−311.3 \times 10^{3}kgm^{- 3}

= 1.12×104kgm−31.12 \times 10^{4}kgm^{- 3}
