Calculate the % of SO42 - in BaSO4, if 2.00 g of SO42 - are present in 5.00 g of BaSO4.

Percentage = 40%

Explanation:

Given dа ta:

Mass of SO₄ = 2.00 g

Mass of BaSO₄ = 5.00 g

Percentage of SO₄ = ?

Solution:

Percentage of any substance can be calculated by following formula.

Percentage = given amount / total amount * 100

Now we will calculate the percentage of SO₄.

Percentage = 2.00 g / 5.00 * 100

Percentage = 0.4 * 100

Percentage = 40%
