Answer 1:

Osmium is the most dense metal! Many people are familiar with lead (11.3 kg/L), but osmium is twice as dense (22.6 kg/L)! Each liter (about 1/4 gallon) of osmium weighs 22.6 kg (50 lbs). For comparison, each liter of water weighs only 1 kg (~2.2 lbs). Some other heavy metals include tungsten and gold (19.3 kg/L), which are almost as dense as osmium.

There are a lot of numbers, but sometimes it's tough to make sense out of these. A small car (Honda Accord) weighs 3400 lbs without any gas or people inside. The same weight would be only 2 cubic feet of osmium. That's about the same space in a paper grocery bag. So, if you had a piece of osmium about the size of a paper grocery bag, it would weigh as much as a new car.
