What is the molecular weight of NaOH?

We are given the compound NaOH, which is sodium hydroxide, and we need to find its molecular weight. To do this, we simply add the atomic masses of all the elements present in the compound.

NaOH contains three elements:

• Sodium (Na)
• Oxygen (O)
• Hydrogen (H)

Now let's look at their atomic masses:

• Sodium (Na) = 23 g/mol
• Oxygen (O) = 16 g/mol
• Hydrogen (H) = 1 g/mol

Now, add them together:

Molecular weight of NaOH = 23 + 16 + 1 = 40 g/mol

So, the molecular weight of sodium hydroxide (NaOH) is 40 grams per mole.
