One litre of feathers would have far less mass than one litre of lead.

Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
No. The mass of one liter of feathers is not greater than the mass of 1 liter of nails. The mass of 1 liter of nails is greater than the mass of 1 liter of feathers. That's why 1 liter of nails is heavier than 1 liter of feathers.
Something that weighs a ton is equal to other things that weigh a ton, therefore a ton of anything is equal to a ton of anything else. Even if it's feathers versus lead or cotton versus cement.
Neither. They both have the same mass. "kg" is a measurement of mass. If you meant volume (the space taken up by the object), the feathers would have the greater volume.
Although they both weigh the same, the kg of feathers would be much more unwieldy, due to its volume. If the feathers were being carried in an open container, on a windy day, when you reached your destination, you would most likely have many less feathers than when you started!
Because of its' mass density. The lead would be much smaller in size.
One kilogram of lead is denser than one kilogram of feathers, so it takes up less space. This makes it easier to carry the lead compared to the same weight of feathers, which would occupy much more volume and be more cumbersome.
Lead is denser than feathers, therefore it would be smaller for the same weight. (feathers may be safer in the long run due to health effects ;) )
Their mass is 1 kg.
207.2/ 6.022*10^23 = 34.4 x 10-23 g, mass of 1 Pb atom For two atoms: 34.4*2= 68.8 x 10-23 g Pb 5.1*10^-23*4.003 g He (atomic mass) / 1 mol He= 20.4*10^-23 g He And the mass of lead is greater.
