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. The answer is 0.338 L (338 mL), but you will have to show the calculations to receive credit on your lab report.

## What is one mole of oxygen at STP?

1 mole of O2 gas at STP=6.022×1023 molecuels of O2 (Avogadro number )=32g of O2 Hence, 1 mole of oxygen gas is equal to molecualr weight of oxygen as well as Avogadro number.

## What is volume of oxygen at STP?

Hence, gram molecular volume of oxygen gas at STP is $22400{text{ c}}{{text{m}}^3}$ and the correct option is (C). Note: The value of pressure, temperature, moles and R should be taken with a proper unit system. The value of universal gas constant (R) should be taken with similar units as of pressure and volume.

## What is the volume of 1 mole at STP?

What is the volume of 1 mole of an ideal gas at STP (Standard Temperature and Pressure = 0 °C, 1 atm)? So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.

## Which of the following is correct for 1 mole methane?

1 mole of CH4 contains 4×6.023×1023=2.408×1024 atoms of hydrogen atoms and 6.023×1023 atoms of carbon atoms.

## What is meant by one mole of oxygen?

One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 10^{23} atoms of oxygen.

## What is the mass of 1 atom of oxygen?

The mass of an oxygen atom = 16 amu.

## How do you find the volume of oxygen?

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.

## What is the volume of 1 mole of gas at RTP?

One mole of any gas has a volume of 24 dm ^{3} or 24,000 cm ^{3} at rtp (room temperature and pressure). This volume is called the molar volume of a gas.

## How many liters does 1 mole of gas occupy at STP?

More specifically, 6.02 x 10^{23} particles (1 mole) of ANY GAS occupies 22.4 Liters at STP. No matter what gas it is!

## How much does 1 mole of methane produce?

Explanation: One mole of methane specifies NA , Avogadro’s number of methane molecules, i.e. 6.022×1023 individual CH4 molecules. And thus it contains 4×6.022×1023 hydrogen atoms .

## How many molecules are present in 1 mole of oxygen gas at STP calculate its mass?

2 Answers. (a,d) 1 mole of 0_{2} gas at STP = 6.022 x 10^{23} molecules of 0_{2} (Avogadro number) = 32 g of 0_{2}. Hence, 1 mole of oxygen gas is equal to molecular weight of oxygen as well as Avogadro number.

## How many moles of oxygen atoms are there in one mole of oxygen molecule?

Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.
