Question
The empirical formula of a compound is CH. If the molar mass of this compound is about $78 \mathrm{~g},$ what is its molecular formula?
Step 1
- The atomic mass of carbon (C) is approximately 12 g/mol. - The atomic mass of hydrogen (H) is approximately 1 g/mol. - Therefore, the molar mass of the empirical formula CH is \(12 + 1 = 13 \, \text{g/mol}\). Show more…
