Why Mass <> moles<> no of molecules are interconverted?
« on: April 24, 2018, 01:16:48 PM »
Here is a reaction below
CH4 (g) + 2O2 (g) = CO2 (g) + 2H2O (g)
in the rection above, the coefficients 2 for O2 and H2O and similarly the coefficient for CH4 and CO2 is one in each case.
Thus according to the above chemical reaction, I can write
1. one mole of CH4 (g) reacts with two moles of O2 (g) to give one mole of CO2 (g) and two moles of H2O (g)
2. one molecule of CH4 (g) reacts with two molecules of O2 (g) to give one molecule of CO2 (g) and two molecules of H2O (g)
3. 22.4 L of CH4 (g) reacts with 44.8 L of O2 (g) to give 22.4 L of CO2 (g) and 44.8 L of H2O (g)
4. 16 g of CH4 (g) reacts with 2 X 32 g of O2 (g) to give 44 g of CO2 (g) and 18 X 2 g of H2O (g)
Now my question is If 'mole' and 'molecule' are different things, then why these relationships can be interconverted? Could you explain it?

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
