The known molar volume of gases is 22.4 L at standard condition. Calculate the molar volume under standard conditions from your data.

I am not sure what the instruction asks. By molar volume, does it mean convert moles to volume.
Like this:
(.004 mol O2)(22.4 L O2/1 mol O2)
=.0896 L

Apparently you have done an experiment in which you have the number of mols of some gas that was generated along with the volume it occupied at STP. I assume you have correctly that to standard conditions. Let's just say you generated 0.500 mol of gas at STP and it had a corrected volume of 11.2 L, then you would have

11.2 L x 1 mol/0.500 mol= ?? molar volume (that is, the volume of 1 mol).

I posted the above response to the original question. Sorry I didn't type in my screen name.

This is the lab (determination of gas constant) I provided the link in the previous post. I'm not sure if you used the volume I obtain. Can you explain to me how to find the molar volume? Is what I did correct or is what DrBob22 did corect? Thanks!

To calculate the molar volume under standard conditions, you need to use the given data, which states that the known molar volume of gases is 22.4 L at standard conditions.

The molar volume represents the volume occupied by one mole of a substance. So, if you have the number of moles of a gas, you can calculate the volume of that gas using the molar volume.

For example, let's say you have 0.004 moles of oxygen gas (O2) and you want to find the volume of this gas under standard conditions. You can use the conversion factor derived from the given data:

0.004 mol O2 x (22.4 L O2/1 mol O2) = 0.0896 L

Therefore, the molar volume of 0.004 moles of oxygen gas under standard conditions is 0.0896 L.
