Hello!
To determine the Kb of gallic acid is actually very simple.
The dissociation reaction of Gallic Acid (HGal) is the following:
HGal+H₂O ⇄ H₃O⁺ + Gal⁻
The equation for converting from Ka to Kb is the following:
So, the Kb is 2,19*10⁻¹²
Have a nice day!

Charles law gives the relationship between temperature of gas and volume of gas.
It states that for a fixed amount of gas, temperature is directly proportional to volume of gas.
V / T = k
where V- volume , T - temperature and k - constant
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
T1 = 250 °C + 273 = 523 K
T2 = 150 °C + 273 = 423 K
Substituting the values in the equation,
V = 251 mL
the new volume is 251 mL
