The molar mass of C₃H₈O₂ is

Question

Quizplus · Accepted Answer

To find the molar mass of C₃H₈O₂, we need to sum the atomic masses of all the atoms in one molecule of C₃H₈O₂. 
- Carbon has an atomic mass of approximately 12.01 g/mol, and we have three carbon atoms. 
- Hydrogen has an atomic mass of approximately 1.01 g/mol, and we have eight hydrogen atoms. 
- Oxygen has an atomic mass of approximately 16.00 g/mol, and we have two oxygen atoms.

Molar mass = (3 x 12.01 g/mol) + (8 x 1.01 g/mol) + (2 x 16.00 g/mol)
= 36.03 g/mol + 8.08 g/mol + 32.00 g/mol
= 76.11 g/mol

Rounding to the nearest tenth gives us the answer of A) 76.0 g.
