Chemistry question

Which one is not a correct mathematical equation for Dalton's law of partial pressure? Here pp = total pressure of the gaseous mixture.

  1. A.pi=xi pi∘p_i = x_i\,p_i^\circ, where xix_i = mole fraction of the iith gas in the mixture and pi∘p_i^\circ = pressure of the iith gas in the pure state✓
  2. B.p=p1+p2+p3p = p_1 + p_2 + p_3
  3. C.p=n1RTV+n2RTV+n3RTVp = n_1\dfrac{RT}{V} + n_2\dfrac{RT}{V} + n_3\dfrac{RT}{V}
  4. D.pi=xi pp_i = x_i\,p, where pip_i = partial pressure of the iith gas and xix_i = mole fraction of the iith gas in the mixture

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
