Question

If 4.00 g Pb (density = 11.34 g/mL) is placed in a graduated cylinder partially filled with water, how many milliliters of water will be displaced?

Answer 1

Mass of lead Pb is 4.00 g and its density is 11.34 g/mL. When it is placed in a graduated cylinder partially filled with water, the volume of lead will be the volume of water displaced by it.

Density of a substance is defined as mass per unit volume of the substance. It is mathematically represented as follows:

`d=(m)/(V)`

Here, m is mass and V is volume. Rearrange the equation to calculate volume as follows:

`V=(m)/(d)`

Putting the values,

`V=(4.00 g)/(11.34 g/mL)=0.353 mL`

Therefore, volume replaced by lead is 0.353 mL
