For experiments, there is 36 g of a 10 concentration sulfuric acid solution. How much sulfuric acid is taken to prepare the solution.

m solution (H2SO4) = 36 g
w (H2SO4) = 10% = 0.1
To find:
m in islands (H2SO4)
m in-va (H2SO4) = w * m solution = 0.1 * 36 g = 3.6 g
Answer: 3.6 g of sulfuric acid was taken.
