CORRECTION 9:33 For question 2 part (d) the final answer is CORRECT; BUT the question asked for the volume and not the number of moles, so we multiply the number of moles (which is 0.05 moles) by the molar volume of any gas (which is 24 dm³) to get the answer 1.2 dm³.

loved the vid !! just a small mistake found though, 9:33 in question 2 (d) the fourth part, it is supposed to be 0.05*24 to give 1.2dm^3 rather than 0.05/24

Thanks for supporting the channel and for pointing it out, but the answer is correct (1.2 dm^3 ), it is just a writing mistake.

Why do we multiply in question 2 d second last part
