$0.105 k g$

#### Explanation:

The density $\rho$, of any substance, is given by
ρ = "Mass"/ "Volume"#
When the RD bottle of capacity $100 \text{ cc} = \frac{100}{100} ^ 3 {m}^{3}$ is filled with a liquid of density given$= 600 k g {m}^{-} 3$

Mass of the liquid $= \text{volume} \times \rho$
$= \frac{100}{100} ^ 3 \times 600 = \frac{6}{100} = 0.06 k g$

Given is mass of the bottle$= \frac{45}{1000} = 0.045 k g$
Mass of the filled bottle$= 0.045 + 0.06 = 0.105 k g$
