A 200mL flask contains oxygen at 200mmHg and a 300 flask contains neon at 100mmHg. The two flasks are then connected so that each gas fills their combined volumes. Assuming no change in temperature, what is the partial pressure of the neon in the final mixtures?

Given the initial volume and pressure, I just set up an equation with the final pressure as our unknown variable, 100mmHg*300mL = 500mL* X
X = 60 mmHg. I am not really sure if this is the correct way to do this problem, but this was just my instinctive approach as soon as I read the problem

(P1)(V1) = (P2)(V2)
(100 mmHg)(300 mL) = (P2)(500 mL)
P2 = 60 mmHg

partial pressures are additive (Dalton's) and you can ignore the volume occupied by the O2 molecules (Kinetic Theory)
