- In room condition the volume is 24dm3
So convert 500cm3 to dm3
1 dm3 equals 1000cm3
x dm3 equals 500cm3
500÷1000=0.5dm3
6.02×10^23 molecules of O2 equals 24 dm3
xmolecules equals 0.5dm3
0.5×6.02 ×10^23 ÷24= 1.25 ×10^22

What is the number density of nitrogen?
The density of ultrapure nitrogen gas at 0 0C and 101,325 kPa is: 1,251 g/L.
How many molecules of nitrogen filled chamber at STANDARD TEMPERATURE AND PRESSURE if the chamber is WIDTH x 300 litres?
At standard temperature and pressure (STP), one mole of any gas occupies approximately 22.4 liters. So, to calculate the number of molecules of nitrogen in the chamber, you would first need to convert the volume of the chamber from liters to moles, then use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules of nitrogen in the chamber.
How many molecules of calcium carbonate are present in its one mole?
If its at STP (standard temperature & pressure) then i think 6 x 10^23 molecules
How do you get moles from molecules?
By taking Avogadro's Number of molecules to form each mole.
What is the exact value of the Avogadro constant in standard form?
The Avogadro constant is approximately 6.022 x 1023, which represents the number of atoms or molecules in one mole of a substance.
How many nitrogen molecules are in a balloon?
The number of nitrogen molecules in a balloon depends on the volume of the balloon and the pressure of the gas inside. However, at standard conditions (1 atm pressure, 0°C temperature), a balloon with a volume of 22.4 liters would contain 6.02 x 10^23 nitrogen molecules, which is known as Avogadro's number.
How do you write Avogadro's number in standard numerical notation?
Avogadro's number is written in standard numerical notation as 6.022 × 10²³. This means it is represented as 602,200,000,000,000,000,000,000, which quantifies the number of atoms, ions, or molecules in one mole of a substance.

What is the amount of molecules of gas in room temperature?
A cubic meter of gas at standard temperature and pressure will have approximately 2.6 x 1025 molecules. This is based on the Avogadro's Number of molecules, (approximately 6.022 x 1023) taking up a volume of around 23 liters. Alternatively, 32 grams of oxygen has Avogadro's number of molecules.
How many molecules are contained in 16.81 of Xe at STP?
To find the number of molecules in 16.81 grams of xenon (Xe) at standard temperature and pressure (STP), first calculate the number of moles using the molar mass of xenon, which is approximately 131.3 g/mol. The number of moles is 16.81 g / 131.3 g/mol ≈ 0.128 moles. Using Avogadro's number (approximately (6.022 \times 10^{23}) molecules/mol), the total number of molecules is 0.128 moles × (6.022 \times 10^{23}) molecules/mol ≈ (7.71 \times 10^{22}) molecules.
Can the volume of a gas at STP can be calculated from the number of molecules of a gas?
Yes, the volume of a gas at Standard Temperature and Pressure (STP) can be calculated from the number of molecules using the ideal gas law. At STP (0°C and 1 atm), one mole of an ideal gas occupies 22.4 liters. Since Avogadro's number (approximately (6.022 \times 10^{23}) molecules) defines one mole, you can convert the number of molecules to moles and then multiply by 22.4 liters to find the volume at STP.
What is Avogadros law?
This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
How many moles of helium gas (he) are present in 7.2 liters of helium gas at standard conditions?
The number of moles of helium is 0,32.
What mass of oxygen contain the same number of molecules as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
