How many grams of H2O and H2SO4 do you need to take to prepare 600 grams of a 20% concentration of sulfuric acid?

Let’s write down given:
m (H2SO4 solution) = 600 g
w (H2SO4) = 20% or 0.2
Calculate:
m (H2SO4) =?
m (H2O) =?
Let’s calculate the mass of sulfuric acid contained in this solution.
w = m (substance) / m (solution), from here we derive the formula for the mass of a substance
m (substance) = w * m (solution),
m (H2SO4) = 0.2 * 600 g = 120 g
Let’s calculate the mass of the mass of water contained in this solution.
m (H2O) = m (solution) – m (substance)
m (H2O) = 600 g – 120 g = 480 g
Answer: m (H2SO4) = 120 g, m (H2O) = 480 g
