The molecular  formula of   organic solvent  is    <em>C6H12</em>


<h2>calculation</h2><h3>find the empirical formula first as in step 1 and 2</h3>

Step 1: f<em>ind the moles of C and H</em>

  • moles =  % composition/molar mass
  •       from periodic table molar mass of C= 12 g/mol while that of H= 1 g/mol
  • moles is  C is therefore = 85.6/12=  7. 13 moles
  •  moles of H=  14.4/1 - 14.4 moles

  Step 2:  <em>calculate the mole  fraction  by dividing each mole by smallest number of mole(7.13)</em>

  • that is C= 7.13/7.13 = 1

         H=  14.4/7.13 =2

the empirical formula is therefore = CH2

<h2>Then calculate the molecular formula from empirical formula</h2>

step 3: divide the  grams molar mass  by empirical formula mass

               empirical formula mass =  12+(1 x2) = 14 g/mol

    = 84.2/ 14 = 6

step 4: multiply  each of the subscript  within the empirical  formula with the value gotten in step 3

  • that is  [CH2]6 = C6H12  therefore the molecular formula = <u>C6H12</u>
