Cecilia created 2.5 liters of a chemical mixture for an experiment. Saline soltution accounted for 12.5% of the mixture. How many liters of saline solution were in the mixture?

a.) 0.3125 liters
b.) 2.1875 liters
c.) 3.125 liters
d.) 31.25 liters

2.5 * 0.125 = ?

To find out how many liters of saline solution were in the mixture, we need to calculate 12.5% of 2.5 liters.

Step 1: Convert the percentage to a decimal by dividing it by 100.
12.5% = 12.5/100 = 0.125

Step 2: Multiply the decimal by the total amount of the mixture.
0.125 x 2.5 = 0.3125

Therefore, there were 0.3125 liters of saline solution in the mixture, which is option a.) 0.3125 liters.
