To determine how much 2% salt solution can be made with the same amount of salt, we need to calculate the total amount of salt in the 700 g 3% salt solution, and then find out how much of a 2% salt solution can be made using that same amount of salt.
Amount of salt in 700 g 3% salt solution:
Salt = 3% of 700 g
Salt = (3/100) * 700 g
Salt = 21 g
To find out how much 2% salt solution can be made, we divide the amount of salt (21 g) by the concentration of the 2% salt solution (0.02):
Amount of 2% salt solution = Salt / Concentration
Amount of 2% salt solution = 21 g / 0.02
Amount of 2% salt solution ≈ 1050 g
Therefore, with the same amount of salt (21 g), approximately 1050 g of a 2% salt solution can be made.
