1/3 Calculate the molar mass of sodium hydroxide (NaOH).

To calculate the molar mass of sodium hydroxide (NaOH), we need to sum the molar masses of sodium (Na), oxygen (O), and hydrogen (H).<br /><br />1. Sodium (Na): 22.99 g/mol<br />2. Oxygen (O): 16.00 g/mol<br />3. Hydrogen (H): 1.01 g/mol<br /><br />Now, add these together:<br /><br />\[ \text{Molar mass of NaOH} = 22.99 \, \text{g/mol} + 16.00 \, \text{g/mol} + 1.01 \, \text{g/mol} \]<br /><br />\[ \text{Molar mass of NaOH} = 40.00 \, \text{g/mol} \]<br /><br />So, the molar mass of sodium hydroxide (NaOH) is 40.00 g/mol.
