Question

ARush made 700 g of 3% salt solution. How much 2% salt solution can he make with the same amount of salt?

Answer 1

Answer: 1050 grams of salt.

Explanation:

1. Find how much salt is in 700g of 3% salt solution.

(3/100)*700g=21g

2. How much solution can you make with 3% salt solution?

(2/100)*x=21g

21g/(2/100)

1050g.

Answer 2

To solve this problem, we can use the concept of the conservation of salt. The amount of salt in the solution remains the same before and after dilution.

Let's calculate the amount of salt in the 3% salt solution that Rush made. Since 3% of 700 g is salt, we have:

(3/100) * 700 g = 21 g of salt

Now, let's determine how much 2% salt solution Rush can make using the same amount of salt (21 g). We'll use the equation:

(amount of salt in solution) = (salt concentration) * (volume of solution)

Let's assume the volume of the 2% salt solution is V grams. The concentration of the 2% salt solution is 2/100 = 0.02. Substituting the values into the equation, we have:

21 g = 0.02 * V

Solving for V, we get:

V = 21 g / 0.02

V = 1050 g

Therefore, Rush can make 1050 grams of the 2% salt solution using the same amount of salt.
