an organic compound contains c=40 h=6.67 if the molecular compound is 30 find its empirical and molecular formula.
Answers
Answer: CH2
Explanation: Carbon =12
Hydrogen = 1
C=40;H=6.67
Carbon Hydrogen
Percentage 40 6.67
Atomic mass 12 1
Moles 40 6.67
12 1
Moles 3.33 6.67
3.33 3.33
1 2
Emperial formula=C1H2 or CH2
CH2 = 30 [given in question]
(12*1*2)n = 30
24n = 30 (dividing both sides by 24)
24n/24 = 30/24
n=30/24
n= 1.25
