What would the mass be, in grams, of 0.89 moles of Cl2?

Mass = 63.19 g

Explanation:

Given data:

Number of moles of Cl₂ = 0.89 mol

Mass in gram = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of Cl₂ = 71 g/mol

by putting values,

Mass = 0.89 mol × 71 g/mol

Mass = 63.19 g

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.
