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: 6.373 milliliters, 868.25 milliliters, 0.278 milliliters, and 420.64 milliliters. How many milliliters of solution will the chemist have after he mixes together the liquids in the beakers?

The chemist will have a total of 6.373 + 868.25 + 0.278 + 420.64 = <<6.373+868.25+0.278+420.64=1295.541>>1295.541 milliliters of solution. Answer: \boxed{1295.541}.

To find the total volume of the solution, we need to add up the volumes of all the liquids in the beakers.

Given volumes of liquids in the beakers:
1) 6.373 milliliters
2) 868.25 milliliters
3) 0.278 milliliters
4) 420.64 milliliters

To find the total volume, add these values together:

6.373 + 868.25 + 0.278 + 420.64

= 1295.541 milliliters

Therefore, the chemist will have 1295.541 milliliters of solution after mixing together the liquids in the beakers.

To find the total amount of liquid in the beakers, you simply add up the amounts in each beaker.

In this case, the chemist has beakers with the following amounts of liquid: 6.373 milliliters, 868.25 milliliters, 0.278 milliliters, and 420.64 milliliters.

To find the total amount of liquid, you add these amounts together:

6.373 + 868.25 + 0.278 + 420.64 = 1295.545 milliliters

Therefore, the chemist will have a total of 1295.545 milliliters of solution after mixing together the liquids in the beakers.
