Calculate the molecular weight of n-butanol
The molecular formula of n-butanol is C4H10O.
To calculate the molecular weight, add up the atomic weights of each element in the molecule:
Carbon (C) = 12.01 g/mol
Hydrogen (H) = 1.01 g/mol
Oxygen (O) = 16.00 g/mol
Molecular weight of n-butanol = (4 x Carbon) + (10 x Hydrogen) + (1 x Oxygen)
= (4 x 12.01) + (10 x 1.01) + (1 x 16.00)
= 48.04 + 10.10 + 16.00
= 74.14 g/mol
Therefore, the molecular weight of n-butanol is 74.14 g/mol.
