Reducing the pressure from 1.0 atm to 0.5 atm would change the number of molecules in one mole of am — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

One mole of any substance always contains exactly Avogadro's number of molecules (6.022 * 10^23) regardless of pressure. Therefore, changing the pressure has no effect on the number of molecules in 1 mole.
