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?

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:

Putting the given values of density and mass of lead, we get

Rearrange the equation, to find the volume

Therefore, volume replaced by lead is 0.353 mL

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
