Density is defined as mass per unit volume, or D = m/v. Solve the density equation for the variable v: *
v = D + m
v = D/m
v = D * m
v= m/D

v = m/D

Explanation:

Density is defined as the mass per unit volume, or D = m/v. Solve for Density equation for the variable v:

With this we are making v Which represents volume the subject so;

With this you multiply both sides by ;

And then the v will multiply the d making it

“vd” and the ‘v’ will cancel the v making it;

So then we divide both sides by d to make v the subject.

So the d cancels the d leaving;

answer; economic order quantity;

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.
