problem

When 0.1000 mole of HA is completely dissolved in 1.000 dm^3 pure water, the pH of the resulting solution is exactly 1.0000. Find, to three significant figures, the pH of a `1.00×108moldm31.00 \times 10^{-8}\:mol\:dm^{-3} ` solution of HA. The autoionisation constant of water `Kw=1.00×1014 K_w=1.00 \times 10^{-14} `. Think step by step and solve the problem below. At the end of your response, write your final answer on a new line starting with “FINAL ANSWER”. It should be an answer to the question such as providing a number, mathematical expression, formula, or entity name, without any extra commentary or providing multiple answer attempts.
