Question

88 g of Carbon Dioxide is collected at STP. The volume of the gas and the number of molecules in the gas are

22.4 L, 2 Avogadro number
44.8 L, 2 Avogadro number
22.4 L, 1 Avogadro number​

Answer 1

Answer:

Avogadro’s law states that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas. The law is approximately valid for real gases at sufficiently low pressures and high temperatures.

At STP, all gas have same volume for 1 mol of gas and that volume is always equal to the 22.4 L.
