Answer

Explanation:

Step1: Recall Avogadro's law

At standard temperature and pressure (STP), equal - amounts of gases contain the same number of molecules and occupy the same volume. The molar volume of any gas at STP is approximately 22.4 L/mol.

Step2: Analyze each option

  • Option 1: 1 mol of (CO_2) has a volume of approximately 22.4 L at STP, and 2 mol of (O_2) has a volume of (2\times22.4 = 44.8) L. So, the volume of 1 mol of (CO_2) is less than that of 2 mol of (O_2).
  • Option 2: 1 mol of (CO_2) and 1 mol of (N_2) both have a volume of approximately 22.4 L at STP, so the volume of 1 mol of (CO_2) is not greater than that of 1 mol of (N_2).
  • Option 3: 2 mol of (O_2) has a volume of (2\times22.4=44.8) L and 1 mol of (N_2) has a volume of 22.4 L. So, their volumes are not the same.
  • Option 4: Since 1 mol of any gas at STP has a volume of approximately 22.4 L, the volumes of 1 mol of (CO_2) and 1 mol of (N_2) gases are the same.

Answer:

The volumes of 1 mol of (CO_2) and 1 mol of (N_2) gases are the same.
