Answer:

an organic compound contain 40% carbon ,6.66% hydrogen and 53.33% oxygen

mole of carbon = 4 mole

for carbon

122

40

= 3.33

3.33

3.33

= 1 atom

for hydrogen

1

6.66

= 6.66

3.33

6.66

= 1 atom

for oxygen

16

53.33

= 3.33

3.33

3.33

= 1 atom

emperical formula CH

2

O

mass 30 gram C is 60/30 = 2 atom

so formula is C2H4O2
