On average, 1 cm of ginger weighs approximately 2 grams. This can vary slightly based on the size and density of the ginger piece.
mass = volume * density Grams are a measure of mass. Liters are a measure of volume. You can use the internet to look up the density for the gas to which you are referring. For instance, hydrogen's density is .0000899 g/cm^3 (grams per cubic centimeters). One liter is 1000 cm^3. 1000 cm^3 * .0000899 g/cm^3 = 0.0899 g Therefore a liter of hydrogen contains about 0.09 grams of hydrogen.
One liter of heavy water contains approximately 11 grams of deuterium.
It would be 2.596. Take the density in grams divided by its volume. So, 27 grams divided by 10.4 cubic cm= 2.56 g/cubic cm which would then be divided by the density of water, which is 1 g/ cubic cm, and the g/ cubic cm cancels out, leaving the answer as 2.596 without a unit. Hope that helps.
The mass of 1000 cm^3 of seawater can be calculated by multiplying its density (1.04 g/cm^3) with the volume (1000 cm^3). Mass = Density x Volume Mass = 1.04 g/cm^3 x 1000 cm^3 Mass = 1040 grams Therefore, the mass of 1000 cm^3 of seawater is 1040 grams.
In short? 1 kg. But more accurately, it depends on the temperature. Room temperature, (23 C) has a density of .997 g/cm^3, and 1 cm^3 of water is 1 mL. So, in 1 Liter, there would be 997 g, or .997 kg.
