2L of sulfuric acid solution contains 456 g of H2SO4 Calculate the mass fraction of the solute, taking into account that the density of the solution is 1.14 g / ml.
Given: m (H2SO4) = 456 g / mol
V (p-pa) = 2 l
P9 (solution) = 1.14 g / ml
Find: w-?
Decision:
m (p-pa) = 2000 * 1014 = 2280 g
w% = 456 * 100/2280 = 20%
Answer: 20%
