How many sodium ions are contained in 99.6 mg of na2so3? the molar mass of na2so3 is 126.05 g/mol.

9.52x10²⁰ sodium ions

Explanation:

First, we need to convert the mass in moles (n)

n = mass/molar mass

The moalr mass is given in g/mol, so let's transform the mass in gram:

1 g 1000 mg

x g 99.6 mg

By a direct simple three rule:

1000x = 99.6

x = 0.0996 g

n = 0.0996/126.05

n = 7.90x10⁻⁴ mol of Na₂SO₃

The ionization reaction is:

Na₂SO₃ → 2Na⁺ + SO₃⁻

So, for 1 mol of Na₂SO₃, will be two moles of Na⁺ (sodium ion), then:

1 mol of Na₂SO₃ 2 moles of Na⁺

7.90x10⁻⁴ x

By a simple direct three rule:

x = 1.58x10⁻³ mol of Na⁺

Avogadro has related the number of moles with the number of the matter: atoms, ions, molecules. So, 1 mol has 6.02x10²³ ions.

1 mol 6.02x10²³

1.58x10⁻³ mol x

By a direct simple three rule:

x = 9.52x10²⁰ sodium ions

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
