Question

in organic compound c=40% and h =6.66 % its vapor density is 90 . calculate its empirical and molecular formula


please answer step by step​

Answer 1

Answer:

What is Name of this Organic Compound

Answer 2

Answer:

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

mole of carbon = 4 mole

for carbon 12240= 3.33 3.333.33= 1 atom

for hydrogen 16.66= 6.66 3.336.66= 1 atom

for oxygen 1653.33= 3.33 3.333.33= 1 atom

emperical formula CH2O

mass 30 gram C is 60/30 = 2 atom

so formula is C2H4O2
