 # The empirical formula of the compound is CH2O . Its molecular weight is 180.The molecular formula of the compound is 12 years ago

Hi,

the wt of emperical = 12+2+ 16= 30

molecular formula = n ( emperical formula)

the way to calculate n:

n =   molecular wt of the compound /  wt of emperical formula

here we hav  n = 180/30 = 6

hence the molecular formula = 6 ( emperical formula)

i.e  6(CH2O) = C6H12O6

good luck & enjoy ur preparation

atomic weight of C=12 ,H=1,O=16 ,

mol. wt. of CH2O is 30

given mol. wt. of compound (nCH2O) is 180,

n=180/30=6

so, compound is C6H12O6

hi,

empirical wt . of compound = 12 + 2 + 16

= 30

mol. wt is 180

thw ratio between the two wt. is called n

n = 180/ 30

=6

so, the mol. formula of compoundwill be

=  ( CH2 o ) 6

= C6 H12 O6
