Answer:

please mark me as brainlist

Answer 2

Given:

       Atomic mass of Sodium = $23u$

       Atomic mass of Oxygen = $16u$

        Atomic mass of Hydrogen = $1u$

To find:

          Molecular mass of Sodium Hydroxide = ?

Steps:

           Molecular mass of $NAOH$ = Atomic mass of $Na$+Atomic mass of $O$+Atomic mass of $H$

                                                      = $23+16+1$

Answer:

           Molecular mass of $NAOH$ = $40u$
