What is the volume of 3 moles of oxygen at STP?

What is the molar volume of 3 moles of He at STP?

Answer. Answer: Explanation: Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=68.1 L .

What is volume of oxygen at STP?

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 the volume in Litres at STP of 3 moles of hydrogen sulphide gas?

The volume is 68.1 L at STP .

How do you find the volume of moles?

At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

What is the volume of oxygen?

What volume of oxygen is required for the complete combustion?

– Hence, we can conclude that 99.667 L of oxygen at NTP is needed for complete combustion of 20 litres of propane measured at ${{27}^{o}}C$ and 760 mm of Hg pressure.

How do you find the volume of oxygen gas?

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 oxygen occupied by 2 moles?

David G. 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 1.5 moles of oxygen gas at STP?

1.5 moles of oxygen at stp = 22.4 x 1.5 = 33.6 litres.
