-What is the density of the spoon in the units of grams per cubic centimeter if its mass is 30 g, and its volume 25 mL?

The density of the spoon : 1.2 g/cm³

Given

mass of the spoon = 30 g

volume = 25 ml

Required

Density

Solution

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

ρ = density  

m = mass  

v = volume  

Input the value :

ρ = 30 g : 25 ml

ρ = 1.2 g/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.
