How many moles are in 50 grams of NaOH?

Step 1: Find the molar mass of NaOH. This is done by adding the atomic masses of sodium (Na), oxygen (O), and hydrogen (H). Sodium has a mass of 23 g/mol, oxygen has a mass of 16 g/mol, and hydrogen has a mass of 1 g/mol.
Step 2: Calculate the total molar mass: 23 g/mol (Na) + 16 g/mol (O) + 1 g/mol (H) = 40 g/mol.
Step 3: Use the formula to find the number of moles: Number of moles = mass / molar mass.
Step 4: Plug in the values: Number of moles = 50 grams / 40 g/mol.
Step 5: Calculate the result: 50 g / 40 g/mol = 1.25 moles.
