If you have 10N of lead and 10N of plumes they will both weigh (9.8*10=) 98kg, if it's on another planet they'll simply have different weights compared to other planets but always be identical to each other on the same planet.

Nitpick, you mixed up newtons and kilograms. "newtons" should be the mass times gravity.
The atmosphere's effect is on the apparent weight of whatever gets weighed, so technically, if the scale says 10 N, you have to add your volume of air to get the real weight, and since feathers and lead have different densities, the volumes and weights will be different. This is usually a really small effect, and may or may not actually matter for this problem.
