12. On ellipse 1, place an " over the location of a focus. Now place an "X" on the orbit where the planet's orbital velocity (speed) would be greatest. On the lines below, explain how you know where to place your "X"

Explanation:

x+x=235

2x=235

235/2

=75x

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

i think it's c. i'm not sure but i think so.
