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
