To calculate the molarity of a solution it is necessary to know

To calculate the molarity of a solution it is necessary to know

- Moles of solute, or mass

- Volume of solution

Explanation:

Molarity means moles of solute, in 1L of solution.

If you firstly know the mass of solute, you can turn into moles like this:

Mass of solute / Molar mass of solute = Moles

Also, you should know the volume.

If those moles are in a certain volume, in 1L (or 1000 mL), how many moles, do you have. You should make a rule of three.

Molarity = moles / L

mmoles / mL

what's the

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.
