how to calculate molecular mass of c2h6

Sure, here are the steps to calculate the molecular mass of C2H6 (Ethane):

1. Identify the number of each type of atom in the molecule. For C2H6, there are 2 Carbon (C) atoms and 6 Hydrogen (H) atoms.

2. Look up the atomic mass of each type of atom. You can find this information on the periodic table. The atomic mass of Carbon (C) is approximately 12.01 amu (atomic mass units) and the atomic mass of Hydrogen (H) is approximately 1.008 amu.

3. Multiply the atomic mass of each type of atom by the number of atoms of that type in the molecule. For C2H6, this would be:

   • Carbon: 2 atoms * 12.01 amu/atom = 24.02 amu
   • Hydrogen: 6 atoms * 1.008 amu/atom = 6.048 amu

4. Add up the total masses to get the molecular mass. For C2H6, this would be:

   • 24.02 amu (Carbon) + 6.048 amu (Hydrogen) = 30.068 amu

So, the molecular mass of C2H6 is approximately 30.068 amu.
