It means there are 22.4 liters of an "ideal" gas at STP (standard temperature and pressure), implying that temperature = 273.15 K and pressure = 1 atm.
liters (l)
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.

how many atoms, molecules and ions are present in one mole of a substance
One atom of sodium weighs more than one atom of oxygen. Thus, one mole of sodium weighs more than one mole of oxygen.
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
One mole of oxygen is 32 g.
There is one critical piece of information missing in the question, i.e. which gas are we talking about since different gas will have different molecular weight. In addition 1 mole of gas occupies volume of 22.4 dm3 at stp. This is equivalent to 22.4 L or 0.0224 m3 per mole of gas. Assuming the molecular weight of the gas Y is x g/mole, then the general solution is as followed: 2263000 tons of gas Y equal 226300*1016*1000g/(x g/mole)*(0.0224 m3/mole) equal 5.15022592e9/x m3 of gas Y
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
There is 1 Avagadro number - so, 6.022 x 1023 molecules in 1 mole of oxygen.
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
One molecule of N2O N 2 O contains one atom of oxygen.
A gram-mole of any gas occupies 22.4 litres. The molecular weight of CO2 is one of carbon plus two of oxygen, 1 x 12 + 2 x 16, in other words 44. That means that a gram-mole of CO2 is 44 grams, which occupies 22.4 litres or 22,400 cc, so its density is 44/22400 or 0.00196 gm/cc. The MW of hydrogen is 2, nitrogen is 18, oxygen is 32, so CO2 is a relatively dense gas.
Zero
There are 32 grams of sulfur in a mole of that element. There are also 32 grams of oxygen in one mole of oxygen as it is found in its natural state (O2).
