Determine the mass fraction of salt in the solution if 12 g of salt is contained in 180 g of the solution.
| March 26, 2021 | education
To find out the mass fraction of salt in the specified saline solution, we use the formula: ωс = mс / m, where mс is the mass of salt (mс = 12 g); m is the mass of the specified brine solution (m = 180 g).
Let’s perform the calculation: ωс = mс / m = 12/180 = 0.06 (6) or 6, (6)%.
Answer: The mass fraction of salt in the indicated saline solution is 6, (6)%.
