Question

An organic compound has an empirical formula (CH2O) and its vapour density is 45. The molecular formula of the compound is


CH2O


C2H4O2


C3H6O3


C6H12O6

Answer 1

Answer:

3 one is your answer!!!!

Answer 2

Answer:C3H6O3

Explanation:

Mr[CH2O] = [12 + (1 x 2) + 16]

= 30

r = 2d

r = 2 x 45

r = 90

x(CH2O) =90

x(30) =90

x = 3

3(CH2O)

=C3H6O3
