Answer:
which one you didnt explain or added attachment?
0.1 M x 0.5L = 0.05 mols HCl.
Adding 25 mL 2M NaOH is
2M x 0.025 L = 0.05 mols NaOH.
What you want to do is to back off very slightly with the NaOH (you might try something like 24.95 mL which I calculate to give 0.00019 M or a pH of 3.7. Inching closer, 24.99 mL would leave H^+ of 4E-5 for pH 4.4. The problem here is two-fold.
hope it helps
If 100cm is 1 metre
Then 0.57 cm =
If less more divides,
Hence 100÷0.57 × 1
= 0.0057 Metres.
Due to lava which heats water where water vapour is comes
The answer is .00834 cg hopefully this helped
