Answer:-
The molar mass of sodium hydroxide (NaOH) is the total mass of one mole of its atoms combined. To calculate it, you add the atomic masses of each element: sodium (Na) is about 22.99 g/mol, oxygen (O) is 16.00 g/mol, and hydrogen (H) is 1.01 g/mol. So, 22.99 + 16.00 + 1.01 = 40.00 g/mol. This means one mole of NaOH weighs 40 grams. Molar mass is important in chemistry for converting between grams and moles, which helps in stoichiometry and preparing solutions with the correct concentration for reactions.
