The molecular weight of lithium hydroxide (LiOH) can be calculated by summing the atomic weights of its constituent elements: lithium (Li), oxygen (O), and hydrogen (H). Here’s the breakdown:
- Lithium (Li): The atomic weight of lithium is approximately 6.94 g/mol.
- Oxygen (O): The atomic weight of oxygen is approximately 16.00 g/mol.
- Hydrogen (H): The atomic weight of hydrogen is approximately 1.01 g/mol.
The molecular formula for lithium hydroxide is LiOH, which consists of one lithium atom, one oxygen atom, and one hydrogen atom. Therefore, the molecular weight (M) is calculated as follows:
[ M(\text{LiOH}) = 6.94 \, \text{g/mol} + 16.00 \, \text{g/mol} + 1.01 \, \text{g/mol} = 23.95 \, \text{g/mol} ]
Thus, the molecular weight of lithium hydroxide (LiOH) is 23.95 g/mol.
