One centimeter cube of methane at STP will contain approximately (2.42 \times 10^{19}) molecules. This is because one mole of any gas at STP occupies 22.4 liters, so 1 cm^3 of methane is equal to (1/(22.4 \times 10^6)) moles, and a mole of methane contains 6.022 x 10^23 molecules.

The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
How do the molecules in an ice cube at 0 degree celsius compare with molecules that are at 20 degree celsius?
The molecules in an ice cube at 0 degrees Celsius move more slowly and are more orderly arranged in a solid structure than the molecules in a substance at 20 degrees Celsius, which are moving quicker and have more kinetic energy. The increased kinetic energy at 20 degrees Celsius results in the substance being in a liquid state instead of a solid state like the ice cube.
Does water or methane have a stronger force of attraction between its particles?
Water has a stronger force of attraction between its particles compared to methane. This is due to hydrogen bonding in water molecules, which creates stronger intermolecular forces compared to the dispersion forces present in methane molecules.
How much methane equals to 1 kg of LPG?
1 kg of LPG is equivalent to around 1.36 cubic meters of methane.
Why is the boiling point of methane much lower than the boiling point of hydrochloric acid?
The boiling point of a substance is determined by the strength of intermolecular forces between its molecules. Methane has weaker London dispersion forces between its nonpolar molecules, resulting in a lower boiling point compared to hydrochloric acid, which has stronger dipole-dipole forces between its polar molecules.
How much is 2 meter cube equal to centimeter cube?
100,000 = 1 cubic meter 200,000 = 2cubic meters
If the size of 1 bacteria is 1 micrometer how much will fit in a centimeter cube?

HOW MUCH IS 30 x 20 x 2 IN CENTIMETERS?
The value equals to 1200 centimeter cube.
How much is 1 cubic centimeter?
It's the same volume as a cube with all sides 1cm long. 1cm^3 = 1 milliliter

How much a 2.5 cm cube of silver weigh?
One cubic centimeter of silver weights 10.497g so 2.5 cubic centimeters of silver would be 26.2425g.
The boiling temperature of water is so much higher than that of methane because water molecules are what?
Water is polar and is strongly hydrogen bonded.
How much density does a ice cube weigh?
The density of ice is approximately 0.92 grams per cubic centimeter. Therefore, the weight of an ice cube would depend on its size and shape. A standard ice cube that is 2 centimeters on each side would weigh around 3.7 grams.
Which is bigger centimeter or megameter?
A megameter is much larger than a centimeter.
How much centimeter is a decimetre?
1 decimeter = 10 centimeter
How much micrometres are in 1 centimeter?
1 centimeter=10,000 micrometers
How much is 8mm?
== 1 centimeter== 10mm == 1 centimeter= 10mm 8 mm= .8 centimeter === ===
