Question 1 Report

Equal volumes of CO2 cnd CO at s.t.p have the same
Answer Details
Equal volumes of CO2 and CO at s.t.p have the same number of molecules. This is because at s.t.p, which stands for standard temperature and pressure (0 degrees Celsius and 1 atm pressure), gases occupy the same volume when they contain the same number of molecules. The molar volume of any gas at s.t.p is 22.4 liters, regardless of the gas's mass or density. Therefore, equal volumes of CO2 and CO at s.t.p will contain the same number of molecules.
