Explanation:
electrons surrounds the necleus. Electrons have a negative charge. Protrons has positive
The answer is 'equal'. Hydroxide ions are OH- and Hydrogen ions are H+. Have you noticed they're opposite charges? Positive + negative = neutral. That's all there is to it :)
Answer: 3.306 mmol
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,
Molarity
n= moles of solute
= volume of solution in ml

According to stoichiometry:
1 mole of
gives 2 moles of 
1.653 mmol of
gives =
of 
Thus number of millimoles of
are 3.306
