When the compound, ba(c2h3o2)2, is mixed with water, the ba(c2h3o2)2 is:
soluble because compounds containing the c2h3o2− ion are soluble in water
insoluble because most compounds containing the c2h3o2− ion are insoluble in water
soluble because all ba+2 compounds are soluble in water
insoluble because no ba+2 are soluble in water

the answer is soluble because compounds containing the C2H3O2− ion are soluble in water

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
