What pressure would be required for neon at 25 degrees C to have the same density as argon at 25 degress C and 1.00 atm?
Didn't I do this for you last night?
P*molar mass = density*RT
Substitute for Ar and conditions and solve for density.
Then use the same formula and the density you calculated for Ar, substitute and solve for P for Ne.
