Number of Na⁺ ions in 2.92 grams of Na₂CO₃ is 24.088 × 10²¹ ions.

Given-

  • Weight of Na₂CO₃ = 2.92 gram
  • Molecular weight of Na₂CO₃ = 106 g/mol

1 mol of Na₂CO₃ contains 2 Na⁺ ions

So, number of Na⁺ ions in 1 mol of Na₂CO₃ is = 6.023 × 10²³ × 2

Moles of Na₂CO₃ = Given weight / Molecular weight = 2.92 gram/106 g/mol

Moles of Na₂CO₃ = 0.02 moles

Number of Na⁺ ions = 6.023 × 10²³ × 2 × 0.02

Number of Na⁺ ions = 24.088 × 10²¹
