Question

An organic compound contains 40% carbon6.66% hydrogen and rest ofoxygen. If the vapor density ofthe compound is 30 then determine its molecular and empirical formula????Gd mrng ✌❤​

Answer 1

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 C  

2

​

H
