Answer:
The answer is 5 mol
Explanation:
Number Of Moles = Mass Of Substance ÷ Mass Of One Mole
Mass of NaOH = Molar Mass of Sodium + Oxygen + Hydrogen
23 + 16 + 1
40 g/mol
Number of Mole = 200/40 = 5 mol
Thus, The number of Moles in 200 grams of Sodium hydroxide is 5 mol

Hey there!
2Na + Cl₂ → 2NaCl
This is a balanced chemical equation.
There are 2 atoms of sodium (Na) on the left, and 2 atoms of sodium (Na) on the right.
There are 2 atoms of chlorine (Cl) on the left, and 2 atoms of chlorine (Cl) on the right.
This means the equation is balanced since there are the same amount of each element on both sides.
Hope this helps!
