2 g/cm³ is the density of the block of wood
Explanation:
To determine density of the block of wood we use the following formula:
density = mass / volume
density of the wood block = 100 g / 50 cm³
density of the wood block = 2 g/cm³

Answer:
ΔG° = - RTLnK is used to find the standard cell potential given the equilibrium constant
Explanation:
for an ideal disolution:
⇒ ΔG = RT∑ni LnXi
∴ ΔG = ( μi - μi*)ni
∴ μ : chemical potential
∴ μ*: chem. potential of the pure component at T and P.
⇒ ΔG = μi - μi* = RT LnXi
for a equilibrium reaction:
⇒ ∑ νi*μi = 0
⇒ ΔGr = ΔG°+ RT Ln Kx = 0
⇒ ΔG° = - RT LnKx
