What is the molar mass of the compound C9H11NO2 ?
To calculate the molar mass of a compound, you need to add up the atomic masses of all the elements present in the compound.
C9H11NO2 contains:
- 9 carbon atoms (C) with a molar mass of 12.01 g/mol
- 11 hydrogen atoms (H) with a molar mass of 1.008 g/mol
- 1 nitrogen atom (N) with a molar mass of 14.01 g/mol
- 2 oxygen atoms (O) with a molar mass of 16.00 g/mol
Now, calculate the total molar mass:
9(12.01) + 11(1.008) + 1(14.01) + 2(16.00) = 99.09 + 11.08 + 14.01 + 32.00 = 156.18 g/mol
Therefore, the molar mass of C9H11NO2 is 156.18 g/mol.
