Explanation:

For example, we will subtract 0.25 cm from 11.5 cm as follows.

                  11.5 cm - 0.25 cm

                 = 11.25 cm

Hence, when we subtract 0.25 cm from 11.5 cm then we get 11.25 cm.

                  = 1.1375 g/ml

or,              = 1.14 g/ml (approx)

Therefore, when we divide 11.375 g by 10.0 mL then it is equal to 1.14 g/ml.

Therefore, we will convert 125 ml into liter as follows.

                  = 0.125 L

Thus, we can conclude that the volume of given flask in liters is 0.125 L.
