An analysis reveals that a substance consists of 26.7% of carbon, 2.24% of hydrogen and 71.1% of oxygen, If the molar mass of th
exis [7]
 the   molecular  formula    is  calculated  as  follows 
find  the  mole  of  each  molecule 
that  is   for  carbon = 26.7/12=  2.23  moles
                   hydrogen=  2.24/1=2.24  moles
                 oxygen=  71.1/16=4.44  moles
find  the   mole  ratio  of  each  element
that  is  divide  all  moles  by  the  smallest  mole(  2.23)

for  carbon=2.23/2.23=1,
  hydrogen =  2.24/2,23=1
  oxygen= 4.44/2.23=  2
the   empirical  formula  = CHO2
therefore  the  molecular  formula=(CHO2)n=270.1
                 { ( 12x 1)  + 1x1) +(16x2)}n=270.1
45n=270.1 
n=6
molecular  formula  is  therefore=(CHO2)6=C6H6O12

Lewis structure NCl3<br><br>please help me

Lewis structure :

•• • ••

:Cl:
••

The dots around the respective atoms represent the number of valence electrons each of the corresponding atoms have. Since nitrogen is more electronegative it is placed within the middle, it can also form the 3 covalent bonds, unlike chlorine which can only form 1 and thus is in the middle of the diagram. This structure has gained stability in that all of the atoms have 8 electrons in its outermost shell, if you were to count the shared electrons for each atom.
