If 7.36 g of sodium metal react, how many grams of sodium hydroxide can be produced

You would also need to know the mol of sodium. After knowing the mol, write down the reaction;

Na + H20 - > NaOH + H2

Use the mol ratio, to find the amount of mol of sodium hydroxide. (Remember to balance the equation first)

After you have the necessary variables, use the following formula:

mass of sodium hydroxide = mol of sodium hydroxide x molar mass (relative/formula mass of sodium hydroxide)

That is how you will find the mass of sodium hydroxide.
