Chemistry problem?! Alexander adds some acid to a solution. The pH of the solution decreases by 2 (from 5 to 2). How many times greater is the concentration of hydrogen ions in the solution, now that Alexander has added some acid to it? *​

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the answer is either b or c

5.6⋅10−^19  j

do you need the explaination?
