A chemist has several beakers full of different liquids that he will use to make a solution. The chemist records the amount of liquid in each beaker: 640.6 milliliters, 908.44 milliliters, 1.5553 liters, and 0.6 liters. How many milliliters of solution will the chemist have after he mixes together the liquids in the beakers?

In order to add the measure of solutions, the amount of liquid in each beaker must have same units. Since the measures of all the beakers do not have the same units, we convert liters into milliliters to make all the units similar. 

We know that :- 

      1 liter = 1000 milliliters 

So,  1.5553 liters =  1555.30 milliliters 

And  0.6 liters = 600 milliliters 

Now, adding all the measurements we get, 

             2 1 1 1

               640.60

         +    908.44

         +  1555.30

         +    600.00

            bottom enclose space space space space space space space space space space space space end enclose

             3704.34 

            bottom enclose space space space space space space space space space space space space end enclose

Thus, the chemist will get 3704.34 milliliters of solution after he mixes together the liquids in the beakers.
