  • 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

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

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

This means the molecular formula is \boxed{\text{C}_{8}\text{H}_{8}}

Earth's climate has changed naturally over the past 650,000 years, moving in and out of ice ages and warm periods. Changes in climate occur because of alterations in Earth's energy balance, which result from some kind of external factor or "forcing" an environmental factor that influences the climate.
