What is the volume of 3.5mol of CO2 gas at STP?
The volume of gas that 3.5 moles of oxygen occupy can be easily found using the relationship of PV=nRT where P is the pressure, V is the volume, n is the moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin.
Gases do not have definite?
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.
If equal amounts of diatomic gases are under the same conditions of temperature and pressure they have the same number of what?
molecules
What is a standard cubic foot of gas?
Because gases follow the principles of Boyle's Law, their volumes are directly proportional to their temperature, and inversely proportional to the pressure they are subjected to. Simply, a given mass of gas, if subjected to a higher pressure, will have a lower volume than before; if warmed to a higher temperature it will have a higher volume than before.Because this property makes it difficult to express how much gas you are actually talking about, scientists standardize the conditions of pressure and temperature when describing an amount of gas, so that those conditions are fixed when doing calculations on an amount. A "standard cubic foot" of gas refers to a volume of 12" x 12" x 12" of the gas (1728 cubic inches) at standard temperature of 0o C and standard pressure of 1 atmosphere or about 14.7 pounds per square inch.
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!
How many moles of oxygen are there in a thirty six centimeter cube of the gas at room temperature and pressure?
What you need to know to work this out is that:- Moles of gases at standard temperature pressure (With P and T constant) are proportional to the volume they occupy, divided by their specific gas constant.
What does Amedeo have to do with moles?
The Avogadro law is: equal volumes of gases have the same number of molecules at constant pressure and temperature.
What is STP is used when discussing gases because gases are so easily affected by temperature and pressure?
STP stands for standard temperature and pressure. It provides a consistent set of conditions (0 degrees Celsius and 1 atmosphere pressure) for comparing and measuring the properties of gases under normal circumstances.
What is the total number of elements in period 2 that are gases at room temperature and standard pressure?
There are three elements in period 2 that are gases at room temperature and standard pressure: nitrogen (N), oxygen (O), and fluorine (F).
What gas is in the fluorine family?
Fluorine and chlorine are the gases in the fluorine family, at standard temperature and pressure.
Which halogens are gases?
Fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2) are halogens that exist as gases at room temperature and pressure. At standard conditions, fluorine and chlorine are diatomic gases, while bromine is a diatomic liquid and iodine is a solid.
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.
What is the total number of elements in group 17 that are gases at room temperature and standard pressure?
its either123or 4
Elements that are gases at SATP?
Gases at SATP (standard ambient temperature and pressure) include elements such as oxygen (O2), nitrogen (N2), hydrogen (H2), and chlorine (Cl2). These elements have low boiling points and exist as gases at room temperature and pressure.
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are five elements in Group 17 (also known as the halogens) that are gases at room temperature at standard pressure: fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2).
Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
Which period table group are made up of only gases?
The first period or row contains only elements that are gases at standard temperature and pressure.
