The percentage of oxygen in NaOH is
The percentage of oxygen in NaOH is _____
1. 40%
2. 80%
3. 55%
4. 60%The percentage of oxygen in NaOH is 40% (Option 1).
Explanation:
NaOH is a white solid inorganic compound also known as Sodium Hydroxide, Lye or Caustic Soda.As we can see it contains Na, O and H elements with Na+ ion and OH- ion. Coming to oxygens composition, we need to find the total molar mass.
Total Molar Mass of NaOH = 23(Na) + 16(O) + 1(H) => 40
Percentage of oxygen = 16/40 * 100 => 40%.
Thus, th percentage of oxygen in NaOH is 40%
