Given data:
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%
