Question

Number of Sodium ions in 0.31 g of Sodium oxide.​

Answer 1

Answer:

Molar mass of sodium oxide = 62 g/mol

In one mole of Sodium oxide, there will be 2 moles of sodium ions (since its formula is Na₂O)

So, in 0.031 g of Na₂O, there will be: 0.031/62 = 0.0005 moles of Na₂O

Now, no. of Na⁺ ions = 2 x 5 x 10⁻⁴ x 6.022 x 10²³ = 6.022 x 10²⁰ is your answer.

Answer 2

Answer:

Molar mass of sodium oxide = 62 g/mol

Molar mass of sodium oxide = 62 g/molIn one mole of Sodium oxide, there will be 2 moles of sodium ions (since its formula is Na₂O)

Molar mass of sodium oxide = 62 g/molIn one mole of Sodium oxide, there will be 2 moles of sodium ions (since its formula is Na₂O)So, in 0.031 g of Na₂O, there will be: 0.031/62 = 0.0005 moles of Na₂O
