The molar mass of isopropanol, also known as isopropyl alcohol or 2-propanol, is approximately 60.10 g/mol. This value is determined by adding up the atomic masses of all the atoms present in its molecular formula, which is C3H8O.
To break it down: isopropanol consists of three carbon (C) atoms, eight hydrogen (H) atoms, and one oxygen (O) atom. The atomic masses are roughly as follows:
- Carbon (C): 12.01 g/mol
- Hydrogen (H): 1.01 g/mol
- Oxygen (O): 16.00 g/mol
Calculating the molar mass:
- Carbon: 3 x 12.01 g/mol = 36.03 g/mol
- Hydrogen: 8 x 1.01 g/mol = 8.08 g/mol
- Oxygen: 1 x 16.00 g/mol = 16.00 g/mol
Now, adding these together gives:
36.03 g/mol + 8.08 g/mol + 16.00 g/mol = 60.11 g/mol
Rounding to two decimal places, we commonly refer to the molar mass of isopropanol as 60.10 g/mol. This value is important for various applications, including chemistry, pharmacology, and industrial processes where precise measurements are necessary.
