Question

An organic compound contain 40.65% C, 8.55% H and 23.77% N. Find empirical formula of compound

plz help me I will mark them as brainlist
it's my humble request
and also in detail information plz.​

Answer 1

Answer:

5.897

Explanation:

I think this is the correct answer

Answer 2

Answer:

Empirical formula = C2H5NO

Molecular mass = 2 ×( Vapour density)

2 × 29.5

= 59.0

empirical formula mass of C4H5NO = 24+5+14+16 = 59

n = (molecular mass) / (Empirical formula mass)

= 59/59 = 1

so, Empirical formula mass = 59

= (C2H5NO)1

Molecular formula mass
