Determine the substance if it is known that the mass fractions of elements are respectively equal: W (c) = 40%, W (o) = 53.33%, W (n) = 6.67%.
x: y: z = 40/12: 53.33 / 16: 6.67 / 1 = 3.33: 3.33: 6.67 = 1: 1: 2
So the simplest formula looks like this:
COH2
Let’s rearrange
CH2O
This formula belongs to the simplest representative of aldehydes – formaldehyde
