Answer:

Gibbs Free Energy (ΔG)

Explanation:

Gibbs Free Energy (G) - Is the energy associated with a chemical reaction that can be used to do useful work. The free energy of a system is the sum of its enthalpy (H) minus the product of the temperature (Kelvin) and the entropy (S) of the system:

G = H -TS--------------------------------------------------------- (1)

ΔG = ΔH - TΔS----------------------------------------------(2)

ΔG = Negative, means the reaction is spontaneous

ΔG = Positive, means the reaction is slow

ΔG = Zero, means the reaction is in equilibrium

Boron has an average mass of 10.81. One isotope of boron has a mass of 10.012938 and a relative abundance of 19.80 percent. The

Andrej [43]

The average mass of an atom is calculated with the formula:

average mass = abundance of isotope (1) × mass of isotope (1) + abundance of isotope (2) × mass of isotope (2) + ... an so on

For the boron we have two isotopes, so the formula will become:

average mass of boron = abundance of isotope (1) × mass of isotope (1) + abundance of isotope (2) × mass of isotope (2)

We plug in the values:

10.81 = 0.1980 × 10.012938 + 0.8020 × mass of isotope (2)

10.81 = 1.98 + 0.8020 × mass of isotope (2)

10.81 - 1.98 = 0.8020 × mass of isotope (2)

8.83 = 0.8020 × mass of isotope (2)

mass of isotope (2) = 8.83 / 0.8020

mass of isotope (2) = 11.009975

mass of isotope (1) = 10.012938 (given by the question)
