What percentage of salt is in a solution if it is obtained from 60 g of salt and 140 g of water?

1. Determine what is the weight of the resulting solution. To do this, add the weight of the salt in the solution to the weight of the water:
140 g + 60 g = 200 g.
2. Determine how many percent of the salt is in the solution. For this, the weight of the salt contained in the solution must be divided by the weight of the solution, and the result obtained must be multiplied by 100%:
60 g / 200 g * 100% = 30%.
Answer: the solution contains 30% salt.
