Samples of the gases O2, N2, CO2 and CO under the same conditions of temperature and pressure contain the same number of molecules represented by X. The molecules of oxygen [O2], occupy V litres and have a mass of 8 g. Under the same conditions of temperature and pressure:(a) What is the volume occupied by:(i) X molecules of N2?(ii) 3X molecules of CO? [C = 12, N = 14, O = 16](b) What is the mass of CO2 in g?(c) In answering the above questions, which law have you used?

1.	Samples of the gases O2, N2, CO2 and CO under the same conditions of temperature and pressure contain the same number of molecules represented by X. The molecules of oxygen [O2], occupy V litres and have a mass of 8 g. Under the same conditions of temperature and pressure:(a) What is the volume occupied by:(i) X molecules of N2?(ii) 3X molecules of CO? [C = 12, N = 14, O = 16](b) What is the mass of CO2 in g?(c) In answering the above questions, which law have you used?
Answer» Samples of the gases O₂, N₂, CO₂ and CO under the same conditions of temperature and pressure contain the same number of molecules represented by X. The molecules of oxygen [O₂], occupy V litres and have a mass of 8 g. Under the same conditions of temperature and pressure: (a) What is the volume occupied by: (i) X molecules of N₂? (ii) 3X molecules of CO? [C = 12, N = 14, O = 16] (b) What is the mass of CO₂ in g? (c) In answering the above questions, which law have you used?
