Question: What is the volume of 2 moles of oxygen?

Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .

What is the volume of 2 moles of O2 at STP?

so 2mol O2 occupies 44.8L of volume at STP.

What is the volume of one mole of oxygen?

Finally, use the fact that one mole of oxygen would occupy a volume of 22.4 L at STP to figure out the volume of the oxygen in this question at STP.

How do you calculate oxygen volume?

Calculate the volume (in cubic meters) of gaseous oxygen using the ideal gas law: multiply the amount of oxygen (in moles) by temperature and the molar gas constant followed by dividing the product by pressure.

Does volume affect number of moles?

Explanation: But volume does not affect the number of moles…… The number of moles is usually an independent variable. And given a volume, we could compress a gas such that many moles of gas could be contained……

What is the volume of 3 moles of oxygen?

We now know that the volume of 2.155 × 10​​-3 moles of oxygen is about 52.88 cm3.

What is the volume of 2.5 moles of o2 at STP?

At STP (Standard Temperature and Pressure:0º C and 1 atm), 1 mole of gas takes up 22.4 L of volume. We’ll learn how to convert back and forth between moles and liters of a gas at STP. Avogadro’s Law is sometimes used as the name for the fact that 1 mole = 22.4 L at STP.

What is the mass of oxygen?

15.999 u

What is r in pV nRT?

The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. … units as: R = 8.314 J/mol·K.

What is the volume of carbon dioxide?

At STP, the molar volume of any ideal gas is 22.4 L. We can identify condition “1” as the volume, temperature, and pressure of the CO2 sample at laboratory conditions and condition “2” as STP.

What is the volume of oxygen required?

The volume of oxygen required for the complete combustion of 8.8 g of propane (C3H8) is: [C=12,O=16,H=1, Molar Volume =22.

What volume of oxygen is required for the complete combustion?

Hence, 0.5 L of oxygen required for the complete combustion of 0.

Does oxygen have volume?

Like most common gases, oxygen expands to fill its container. … You may know that an oxygen cylinder contains some number of cubic feet of oxygen, but the cylinder doesn’t look like it could possibly hold that much. It’s the compressibility of oxygen that makes it possible to squeeze a mass of gas into a small space.

Is moles directly proportional to volume?

A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas. This is stated as Avogadro’s law.

Why are moles and volume directly proportional?

Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

What happens to volume when moles increases?

Avagadro’s Law- Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.
