Cabbage marinade contains 100 grams of water, 250 grams of 6 percent vinegar, 200 grams of sugar and 60 grams of table salt. Calculate the mass fraction of sugar and vinegar.
Find the mass of vinegar in the solution.
W = m (substance): m (solution) × 100%,
m (substance) = (m (solution) × W): 100%.
m (vinegar) = (250 g × 6%): 100% = 15 g.
(m (solution) = 100 g (water) + 200 (vinegar) + 200 g (sugar) + 60 g (salt) = 610 g.
W (sugar) = (200g: 610g) × 100% = 33%.
W (vinegar) = (15g: 610g) × 100% = 2.46%.
Answer: 33%; 2.46%.
