How many liters of a 0.75 M solution can be made with 75 g of lead (II) oxide

The answer to your question is 0.448 l or 448 ml

Explanation:

Data

Volume = ?

Concentration = 0.75 M

mass of PbO = 75 g

Process

1.- Calculate the molar mass of PbO

PbO = 207 + 16 = 223 g

2.- Calculate the number of moles in 75 g

                        223 g 1 mol

                          75 g  x

                              x = (75 x 1)/223

                              x = 0.336 moles of PbO

3.- Calculate the volume

Molarity = moles / volume

-Solve for volume

Volume = moles / Molarity

-Substitution

Volume = 0.336 / 0.75

-Result

Volume = 0.448 l or 448 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.
