The mass of a given volume of a material is dependent on the material's density, and thus its molecular weight. So, this will differ for every type of material, and there is therefore no absolute weight for 1ml (cm3) of a material.
The only universal measure of mass that holds for all materials is the 'mole.'
A mole is defined as 6.022 x 1023 atoms of a given substance. Multiplying the Atomic Mass of a given element or molecular weight of a given compound by this number yields the mass of one mole of the element, in grams. If the density of a given substance is known, the mass per cm3 can then be calculated.
Frequently in chemistry, the density of a substance is compared to the density of water (H2O), which is 1g/ml.
The mass of 1 cm3 of water is approximately 1 gram.
The mass of 50 cm3 of water is 50 grams. This is because water has a density of 1 g/cm3, so for every 1 cm3 of water, the mass is 1 gram.
No
If its mass is 0.6 g and its volume is 1 cm3 , then its density is 0.6 g per cm3 .
Density of Mountain Dew- 1.02 g/cm3 (volume=380 ml (1 ml= 1 cm3), mass=389 g.) Density of Diet Mountain Dew- 1 g/cm3 (volume=380 ml (1 ml= 1 cm3), mass=380 g.)
The volume is (6 x 3 x 1) = 18 cm3 . The density is (whatever amount of mass is contained in 1 cm3 ) per cm3 , or (1/18 of the mass of the total solid you described) per cm3 .
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
"Gram" is a unit of mass. "Cm3" is a unit of volume. So the answer depends on what substance is in the cm3 . If the cm3 is empty, then there are no grams in it. If it's full of air, then there's only a small fraction of a gram in it. If it's a cm3 of water, then there's roughly 1 gram of mass in it. If it's a cm3 of gold, then there are about 19 grams of mass in it.
The mass of 1 cm3 of silver is approximately 10.5 grams. Silver has a density of 10.5 g/cm3, so for every cubic centimeter of silver, the mass is 10.5 grams.
I am assuming you mean the density is 4.0 g/ cm3 and the displaced H20 is 3.0 cm3 (3 mls when converted to cm3). Look at the units that should tell you how to solve the problem. Your answer must in g (mass), thus you take 4.0 g/cm3 times 3.0 cm3. Units are treated like numbers, for example 3 times 1/3 equals 1 - both 3's cancel leaving only 1 time 1 which equals 1. In this case you have 4 g/cm3 times 3.0 cm3, cm3's cancel leaving only g as your unit at the end. The rest is for you to solve! Enjoy your problem.

1 Litre = 1000 cm3 and 1 kilogram = 1000 grams So 0.768 gms per cm3 = 0.768 kilograms per Litre. Then mass of 155211 L = 155 211 * 0.768 = 119 202.048 kilograms. 0.768 grams per cm3
