Answer:

The percentage composition of oxygen in sodium hydroxide = 40%

Explanation:

First, calculate the mass of the entire compound:

Mass of the entire compound = 23 + 16 + 1

                                                 = 40g

Now we can calculate the percentage composition of oxygen by using the following formula:

Percentage Composition of oxygen = Mass of element        ×   100

                                                             Mass of compound             1

                                                            =        16    ×     100

                                                                     40             1

                                                            =       40%

                                                                             Hope this helps! :)
