Hello there!
In this case, given the Henderson-Hasselbach equation, it is possible for us to compute the pH by firstly computing the concentration of the acid and the conjugate base; for this purpose we assume that the volume of the total solution is 0.025 L and the molar mass of the sodium base is 234 - 1 + 23 = 256 g/mol as one H is replaced by the Na:
And the concentrations are:
Then, considering that the Ka of this acid is 2.5x10⁻⁵, we obtain for the pH:
Best regards!

Answer:
Explanation:
Given that,
The frequency of a the microwaves is
We need to find the wavelength. Al electromagnetic wave travel with speed of sound. We know that,
So, the wavelength of the microwaves is 0.03 m.
