Look up the density on the Periodic Table. You won't learn anything if we just spoon-feed you!
Cheers.
1 liter of platinum corresponds to 1,000 milliliters, which is equal to 1,000 cubic centimeters. The density of platinum is 21.45 grams per cubic centimeter, so 1,000 cm^3 would have a mass of 21,450 grams, or 21.45 kg. So to answer your question, a liter of platinum has a mass of 21.45 kg, and a weight of 47.3 lb.
The density of borosilicate glass is approx. 2,23 g/cm3.
The number listed most frequently on the www for the density of pure iron at room temperature is 7.874 grams of mass per cubic centimeter. On Earth, 7.874 grams of mass weighs 0.0772 newtons (rounded), or 0.278 ounce avdp.
Nitric acid has the formula of HNO3. It has a density of 1.5129 grams per cubic centimeter. This means that 2500 cubic centimeters has a mass of 3.78 kilograms.
The density of ununoctium is not known.
Density of latex is 0.920 - 0.960 grams per cubic centimeter.
It would weigh 1,342 pounds.
One cubic centimeter of water would fit into that cup, and it would weigh 1 gram.
A centimeter of what? Air? Lead? Water? If you want to weigh something, first you need to know all three dimensions of the object, since you can only weigh 3-dimensional objects. So, assuming the object is 1cm X 1cm X 1cm, you have a cubic centimeter. Now you need to know the density of the object. Obviously, a cubic centimeter of marshmallow will weigh less than a cubic centimeter of lead: A cubic centimeter of lead weighs 11.34 grams A cubic centimeter of water weighs 1 gram Silicone = 2.3 grams A cubic centimeter of a concentrated mass of neutrons (a former star) = 800,000,000 tons!!!!!

The given answers are confusing and misuse units. The density at room temperature of the most common isotope of Pu (i.e., 239) is 19.816 grams per cubic centimeter (g/cm^3). One cubic inch equals 16.387 064 cm^3. 19.816 * 16.387 064 = 324.73 g/in^3.
340 a ml is a cubic centimeter.
The density of borosilicate glass is approx. 2,23 g/cm3.
One cubic centimeter of silver weights 10.497g so 2.5 cubic centimeters of silver would be 26.2425g.
1,100,000,000,000 kilograms = 1.21254244 × 109 short tons
Biodiesel has a density 0.88 grams per cubic centimeter. This converts to about 7.34 pounds per gallon.
1 cubic centimeter of neutron star stuff would weigh as much as 1000 aircraft carriers
