How are moles masses or volumes of gases calculated from one another for a gas at STP?
Hey I'm a student too:) it's pretty tricky so don't feel bad if you don't understand.
You have a few choices,
you can use the ideal gas laws: 1 = (PV)/(nRT) --> and you know at STP (standard temperature and pressure) P = 101.3kPa, and you know T = 0 degrees C = 273K
Or you can use knowledge that n = m/M (number of moles = mass/molar mass)
V = n x 22.4 (volume = number of moles x 22.4L)
n = number of particles / 6.02 x 10^23
Hope this helps:) good luck!

Where did amedeo avogadro do his science work?
Avogadro came up with what we know as Avodgadro's number. The idea is that at a specific temperature and pressure, equal volumes of two gases will contain the same number of atoms or molecules. This idea was the basis for relative molecular masses, i.e. ways to compare samples that have different atomic masses using the number of atoms or molecules in the sample.
Gases are good insulators because their molecules are?
because they are so far from one another and they are scattered unmannerly, so compressing means to bring them closer..
How can different types of matter be distinguished from each other?
The short answer is by their properties. If you mean solids, liquids and gases then you look at whether they have fixed shapes and fixed volumes or not. If you mean different substances, then you look at properties such as melting point, appearance and chemical reactions.
3 properties of matter?
The three properties of matter are solids, liquids, and gases.
What is gay-lussac's law of combination volumes?
The ratio between reactant gases and product gases are simple integers.
What rhymes with gases?
Passes, masses
Why volumes of gases are converted into STP conditions and then compares?
Since volumes of gases change with temperature and pressure, a standard value of temperature and pressuure is chosen to which gas volumes are referred. Hence volumes of gases are converted into S.T.P. conditions and then compared easily.
what is it called when gases are forced or squeezed into smaller volumes?
compressibility
What did early chemists discover about reactions involving the combination of gases?
Early chemists discovered that at constant temperature and pressure, the volume of gases consumed and produced is equal to the ratio of the stoichiometric coefficients. This is called the law of combining volumes and was discovered by Gay-Lussac.
The law of combining volumes applies only to gas volumes?
The law of combining volumes states that the ratios of volumes of reacting gases can be expressed as small whole number ratios. This law is based on the assumption that gases behave ideally, meaning they occupy the same amount of space as predicted by the ideal gas law. Therefore, this law does not apply to the volumes of liquids or solids.
Do gases have definite mass?
Different gasses have different masses.
What is Gay-lussac?
A law stating that the volumes of gases undergoing a reaction at constant pressure and temperature are in a simple ratio to each other and to that of the product.Gay-Lussac's law, known as the law of combining volumes, states that: The ratio between the combining volumes of gases and the product, if gaseous, can be expressed in small whole numbers
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of gases is inversely proportional to the square root of their molar masses. By comparing the molar masses of the two gases, you can determine which gas effuses faster. The gas with the lower molar mass will effuse more quickly.
What equal volumes of gases under the same conditions of temperature and pressure have equal?
Equal volumes of gases under the same conditions of temperature and pressure have an equal number of molecules, according to Avogadro's Law. This relationship allows for direct comparisons of the amounts of different gases.
Which property of gases makes it possible to fill large volume of gases in small cylinders?
The property of gases being compressible allows them to be densely packed into small volumes, such as cylinders. This means that gas particles can be squeezed close together, reducing the overall size of the gas. This compressibility allows for the storage of large volumes of gases in relatively small containers.
Who said gases are made of particles separated by empty space because gases can be squashed and yet return their masses?
Democritus
