Hello there!
In this case, according to the given information, it turns out possible for us to realize this problem is solved via the ideal gas equation:
As we can calculate the moles of propane given the pressure, temperature and volume as shown below:
Finally, since the molar mass of propane is 44.1 g/mol, we calculate the mass by following the shown below mole-mass conversion factor:

The [H₃0⁺] of the solution : 1.778 x 10⁻¹² M
<h3>Further explanation </h3>pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH of solution = 11.75
the [H₃0⁺] of the solution :
