density of water is 1g cm-3?
160298
The density of water is about 1 g/cm3, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 °C.

Conversion Table. 1 gram (g) = weight of 1 cubic centimeter (cc, cm3) of pure water at temperature 4 °C = 1000 milligrams (mg) = 0.001 kilogram (kg).

Specific gravity is the density of a substance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density (but without any units).

Taking the density of water to be 1g/mL, 1000mL of water= 1000g water. =3.34*10^25 molecules of water. Or 3.34*10^23 molecules in 1ml. 18 g (molar mass) of H2O has ~6 x 10 to the power of 23 molecules.

The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.

Density is normally measured using units of g/cm3 for smaller amounts, and kg/m3 for larger amounts. Calculations of density can be represented by a triangle: To work out the mass, calculate density x volume: to work out density, it is mass ÷ volume, and for volume it is mass ÷ density.

The density of water is 1g/(cm3) so in 1 gallon of water ( about 3.785 Liters or 3785 cm3) the mass of the water is, 3785g. 1 mole of 6.02x1023 molecules of water is equal has the mass in grams equal to the molecular weight or 18 grams per mole. so 3785 grams corresponds to about 1.265 x 1026 molecules of water.

The specific gravity (density relative to the density of water) of hydrochloric acid solution is 1.18 g/mL.

At maximum density of water and at a temperature of 4 °C the volume of 1 milliliter is equal to a mass of 1 gram. A volume of 100 mL of water at the same given conditions has a mass equal to 100 grams.

The density of water is approximately 1 kG/liter, depending on temperature. ... Therefor, 5kG oil > 5 liters oil. 5kg of o. The density of water is approximately 1 kG/liter, depending on temperature.

The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2oF (4oC), because this temperature allows water to assume its maximum density.

One mole of water has a mass of 18 grams and a volume of 18 mL (as the density of water is 1 g per cm3). It contains Avogadro's number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23 molecules (assume you can do the maths…)

If density of water is 1gm/ml then weight of water present in one litre of water is 1000 grams. So number of moles will be 1000/18 moles which is equal to 55.55 moles.

If a liter of a liquid weighs 1 kilogram, its density is 1 kg/m^3. Water is known to come very close to this density. For other liquids, it varies.

It had a mass equal to the mass of 1 dm3 of water under atmospheric pressure and at the temperature of its maximum density, which is approximately 4 °C. 2019: as of 20 May, the kilogram is redefined in terms of the Planck constant as approved by the General Conference on Weights and Measures (CGPM) on 16 November 2018.
