Match each sodium salt solution with its corresponding number of sodium ion moles.
-100 mL of 0.2 M sodium hydroxide solution

Question

Quizplus · Accepted Answer

The number of sodium ion moles can be calculated using the formula:
moles of ion = concentration × volume in liters

For sodium hydroxide solution:
moles of Na+ = moles of OH- (since it is a 1:1 ratio)
moles of Na+ = 0.2 × 0.1 (since volume is given in mL)
moles of Na+ = 0.02

Therefore, the best choice is B.
