Stephanie added 2.334 ml of water to a beaker, and she then added another 0.31 ml of water to the same beaker. how much water was in stephanie's beaker?

Explanation:

Since, Stephanie is adding water in a beaker already having water. This means that by adding both the given volumes we can calculate the total volume of water present within the container.

Therefore, initially there was 2.334 ml of water in the beaker. Then, 0.31 ml of water is added into it.

Hence, the final volume of water will be as follows.

                     Final volume = 2.334 ml + 0.31 ml

                                            = 2.644 ml

Thus, we can conclude that there was 2.644 ml of water present in Stephanie's beaker.
