Answer:
She made 25 grams of 40% salt solution.
Step-by-step explanation:
Given : Maya added 5 grams of salt into 20 grams of 50% salt solution. She made ___ grams of ___% salt solution.
To find : The blank space or she made how many grams of which % of the solution ?
Solution :
First we find the number of grams,
As the total weight of the solution which is derived from adding 5 grams into 20 grams is
T = 5 + 20 = 25 grams
Now, The % solution
It can be find by dividing the amount of salt initially by the total amount of the resulting solution multiplied by 100.
[tex]C = \frac{20\times 0.5}{25}\times100[/tex]
[tex]C = \frac{10}{25}\times100[/tex]
[tex]C = 10\times 4[/tex]
[tex]C =40\%[/tex]
Therefore, She made 25 grams of 40% salt solution.
