Answer:
The concentration of the resulting solution is 10%.
Step-by-step explanation:
Given : Maria has added 4 liters of pure water to 4 liters of a 20% sugar syrup.
To find : What is the concentration of the resulting solution?
Solution :
Maria has 4 liters of a 20% sugar syrup,
i.e. [tex]A=20\%\text{ of }4[/tex]
[tex]A=\frac{20}{100}\times4[/tex]
[tex]A=\frac{4}{5}[/tex]
[tex]A=0.8[/tex]
She add 4 liters of pure water to 4 liter
New solution is 4+4=8 liters
The concentration of the resulting solution is
[tex]C=\frac{0.8}{8}\times 100[/tex]
[tex]C=10\%[/tex]
Therefore, The concentration of the resulting solution is 10%.
