Moles of cations are in 1.35 mol of K2SO4
KatRina [158]

1.35 mole of K₂SO₄ contain 2.7 moles of cation.

Cations are positive ions. They are the ions of metallic elements.

To obtain the answer to the question, we'll begin by calculating the number of mole of cations in 1 mole of K₂SO₄.

K₂SO₄ (aq) —> 2K⁺ (aq) + SO₄²¯ (aq)

<h3>Cation => K⁺</h3>

From the balanced equation above,

1 mole of K₂SO₄ contains 2 moles of K⁺ (i.e cation).

Finally, we shall determine the number of mole of cation in 1.35 mole of K₂SO₄. This can be obtained as follow:

1 mole of K₂SO₄ contains 2 moles of K⁺ (i.e cation).

Therefore, 1.35 mole of K₂SO₄ will contain = 1.35 × 2 = 2.7 moles of K⁺ (i.e cation).

Hence, we can conclude that 1.35 mole of K₂SO₄ contain 2.7 moles of cation
