Explanation

## Step1: Determine the molar mass of NaOH### The molar mass of NaOH is the sum of the atomic masses of its elements: Na (22.99 g/mol), O (16.00 g/mol), H (1.01 g/mol). So, molar mass of NaOH = 22.99 + 16.00 + 1.01 = 40.00 g/mol.## Step2: Use the formula to find moles### Use the formula: Substitute the given values:
