<h3>What is an ideal gas equation?</h3>The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
Given data:
= 720 mmHg
= ?
= 2.5 mol
= 3.2 mol
= 34 L
= 45 L
Formula
Combined gas law
= 696.32 mmHg
Hence, 696.32 mmHg is the final pressure of the gas.

Answer:
The pH of the solution is 11.48.
Explanation:
The reaction between NaOH and HCl is:
NaOH + HCl → H₂O + NaCl
From the reaction of 3.60x10⁻³ moles of NaOH and 5.95x10⁻⁴ moles of HCl we have that all the HCl will react and some of NaOH will be leftover:
Now, we need to find the concentration of the OH⁻ ions.
Where V is the volume of the solution = 1.00 L
Finally, we can calculate the pH of the solution as follows:
Therefore, the pH of the solution is 11.48.
