Molar Mass of C3H6O3

How to work out the molar mass of C3H6O3

1. Count the atoms of each element in C3H6O3: 3 C, 6 H and 3 O.
2. Multiply each count by the element's atomic weight: 3 × 12.011 = 36.033; 6 × 1.008 = 6.048; 3 × 15.999 = 47.997.
3. Add the results: 36.033 + 6.048 + 47.997 = 90.078 g/mol.
