The empirical formula of styrene is CH; its molar mass is 104.1 g/mol. What is the molecular formula of styrene

Sagot :

  • The atomic mass of carbon is 12.011 g/mol.
  • The atomic mass of hydrogen is 1.00794 g/mol.

This means the molar mass of CH is

[tex]12.011+1.00794=13.01894 \text{ g/mol}[/tex]

Dividing the given molar mass by this,[tex]\frac{104.1}{13.01894} \approx 8[/tex]

This means the molecular formula is [tex]\boxed{\text{C}_{8}\text{H}_{8}}[/tex]
