Atomic number is same number as the protons...
Neutrons = Mass number - Atomic number ( protons)
Electrons are same number as protons unless the element has a charge..
If it has a charge of +2 it means that the element has 2 less electrons than the neutral atom. If it has a charge of -2 it means that the element has 2 more electrons than what it is supposed to..

Explanation:
Step 1: Write the neutralization reaction between oxalic acid and sodium hydroxide.
H₂C₂O₄ + 2 NaOH = Na₂C₂O₄ + 2 H₂O
Step 2: Calculate the moles of oxalic acid
The molar mass of H₂C₂O₄ is 90.03 g/mol. The moles corresponding to 153 mg (0.153 g) are:
Step 3: Calculate the moles of sodium hydroxide
The molar ratio of H₂C₂O₄ to NaOH is 1:2.
Step 4: Calculate the molarity of sodium hydroxide
