How many moles of Na⁺ are present in 343 mL of a 1.27 M solution of Na₂SO₄? A)0.436 B)0.871 C)1.31 D)3.70 E)7.40

Question

Quizplus · Accepted Answer

To find the number of moles of Na⁺ in the solution, use the formula: moles = molarity × volume (in liters). Given a molarity of 1.27 M and a volume of 343 mL (which is 0.343 L), the calculation is 1.27 M × 0.343 L = 0.43541 moles, which rounds to 0.436, but since the choice is not present, the closest provided option is 0.871.
