Guida verificata passo dopo passo1
Identify the elements present in the compound NaOH: sodium (Na), oxygen (O), and hydrogen (H).
Find the atomic masses of each element from the periodic table: sodium (Na) ≈ 22.99 g/mol, oxygen (O) ≈ 16.00 g/mol, and hydrogen (H) ≈ 1.01 g/mol.
Add the atomic masses of all atoms in the formula to find the molar mass: \(\text{Molar mass of NaOH} = 22.99 + 16.00 + 1.01\) g/mol.
Sum these values to get the total molar mass of NaOH.
Use this molar mass to compare with the given options and select the correct one.
