Maria has added 4 liters of pure water to 4 liters of a 20% sugar syrup. what is the concentration of the resulting solution?

10%

Step-by-step explanation:

Given : Maria has added 4 liters of pure water to 4 liters of a 20% sugar syrup.

Total solution : 4+4 = 8 liters

Amount of sugar in 4 liters of 20% sugar syrup will be

Amount of sugar in 4 liters =20% of 4 liters

Amount of sugar in 4 liters = 0.20 x 4 = 0.8 liters      [we can write 20%= 0.20]

Then,  the concentration of the resulting solution would be :

Hence, the concentration of the resulting solution= 10%

might be the correct answer will be question number 2
