Mass of lead Pb = 4.00 g (given)
Density of lead= 11.34 g/mL (given)
When lead is placed in a graduated cylinder which is partially filled with water, the volume of lead will be the volume of water displaced by it.
Density (d) of a substance is the ratio of mass (m) to the volume (m) of the substance.
The formula of density is given as:
[tex]d= \frac{m}{v}[/tex]
Putting the given values of density and mass of lead, we get
[tex]11.34 g/mL= \frac{4.00 g}{v}[/tex]
Rearrange the equation, to find the volume
[tex]V= \frac{4.00 g}{11.34 g/mL}[/tex]
[tex]V= 0.3527 mL \simeq 0.353 mL[/tex]
Therefore, volume replaced by lead is 0.353 mL
