Find the inversion temperature (in K) of van der Waals gas with constants a = 0.14 Pa∙m⁶/mol² b = 3.9∙10⁻⁵m³/mol. Write the answer in decimal representation rounding it to 2 significant figures. Thanks for all your help!

    5.5 n======    assuming that      we have      m = 0.145 kg    a = 38 m/s²therefore    5.51 n, but two significant figures.final answer: 5.5 n

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then   

Dshould be the right answer i think
