Calculate the weight of carbon which is burnt with excess of oxygen to form 22.4litre of CO2 at NTP 1).4g 2).6g 3).12g 4).24g
Hi,
Given reaction is C + O2 --------> CO2
Now, we know that 1 mole of Carbon reacts with 1 mole of Oxygen to form 1 mole of Carbon dioxide.
Hence, let x be the mass of Carbon initially. Now moles of C are = x /12 , and now it will be equal to 1.
i.e. x = 12 g
Hope it helps.
