The solution contains 140 kg of salt, which is equal to the mass of the solution if the salt in it is 35%.

To determine the weight of the salt in the solution, the initial volume of the solution must be divided by 100% and multiplied by the percentage of salt in the solution, that is, by 35%. Determine the weight of the salt in the solution:

140: 100 * 35 = 49 (kg).

Answer: The weight of the salt in the solution is 49 kg.
