thanks and can you tell me
Why it's one mole of nitrogen atoms why it's not one mole of nitrogen molecules or ions?
And something more..
How i know if 1=2 and 1.5=3 in the empirical formula because sometimes 1=1 like CH2
Here Carbon is 1
And here C2H3
Carbon is 1 too
and Hydrogen is 1.5
how to know that please and thanks
