To get 150g of a 12% solution, do you need more salt than to get 120g of a 15% solution?
True/False
I just found my answer. False!
I meant, Yes or No.
Looks to me like the answer should be no. Both are 18.
To determine whether you need more salt to get a 150g 12% solution compared to a 120g 15% solution, we can calculate the amount of salt required for each solution.
To find the amount of salt needed for a solution, we can use the formula:
Amount of salt = Total weight of the solution * Percentage concentration
For the 150g 12% solution:
Amount of salt = 150g * 0.12 = 18g
For the 120g 15% solution:
Amount of salt = 120g * 0.15 = 18g
As we can see, the amount of salt required for both solutions is exactly the same, which means that you do not need more salt to obtain the 150g 12% solution compared to the 120g 15% solution.
Therefore, the answer is False.
compare 0.12 * 150 with 0.15 * 120
And a question cannot be true or false -- it is a question.
