Which of the following samples will have the greatest volume at stp? 22 g co 22 g he 22 g o2 22 g cl2 all of these samples would have the same volume at stp.

Explanation:

Following Avogadro's principle, under ideal condtions, the volume of the gases at the same conditions of temperature, and pressure, is proportional to the number of molecules.

Then, you can calculate the number of molecules for each of the gases to determine which is the sample with the greatest number of molecules and, hence, which will have the greatest volume at STP (standard temperature and pressure).

The formula to calcualte the number of molecules (in moles) is:

Then, since the mass is the same (22 g) for the four options, the result will be dependent on the molar mass: the gass witht the smallest molar mass will give the largest number of moles for 22 g, and will have the  greatest volume.

a) 22 g CO:

b) 22 g He:

c) 22 g O₂

d) 22 g Cl₂

Conclusion: since He has the smallest molar mass, the sample of 22 g of He gas will have the greatest volume at STP.
