When 13 g of sodium sulfate was dissolved in 400 g of water, a solution was formed. Determine the concentration of the solution.
| December 14, 2020 | education
solution concentration = mass of substance / mass of solution × 100%
mass of solution = mass of substance + mass of water = 13 + 400 = 413 g.
solution concentration = 13/413 × 100% = 3.14%
answer: solution concentration 3.14%
