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
