Emily added 5 grams of water into 20 grams of 50% salt solution. She made _ grams of _% salt solution.

1 answer:

8 0

For the first blank, the answer should be the total weight of the solution which is derived from adding 5 grams and 20 grams. The answer would be,

T = 5 + 20 = 25 grams

For the second blank, the % solution is derived by dividing the amount of salt initially by the total amount of the resulting solution. This is as shown below.

C = ((20 x 0.5) / 25) x (100%)

Simplifying,
C = 40%

Answers:
a. 25 grams
b. 40%
