How to Calculate the Molecular Weight of LiOH

To calculate the molecular weight of LiOH, follow these steps:
Identify Atomic Weights:
- Lithium (Li): 6.94 g/mol
- Oxygen (O): 16.00 g/mol
- Hydrogen (H): 1.01 g/mol
- Lithium (Li): 6.94 g/mol
Sum the Atomic Weights:
For LiOH:
[
\text{Molecular Weight} = 6.94 (\text{Li}) + 16.00 (\text{O}) + 1.01 (\text{H}) = 23.95 \, \text{g/mol}
]
For LiOH·H₂O:
[
\text{Molecular Weight} = 6.94 (\text{Li}) + 16.00 (\text{O}) + 1.01 (\text{H}) + 15.99 (\text{H₂O}) = 39.99 \, \text{g/mol}
]
