Kia is doing an experiment in science lab. She is given a beaker containing 100 g of liquid. The beaker has markings on the side for measuring volume. The water comes up to the 100 mL mark. Kia puts the liquid on a hot plate by mistake. By the time she realizes the mistake, half of her liquid has evaporated. Kia still needs 100 g of liquid for her experiment. To find out how much liquid she has to replace, she needs to re-weigh her liquid. However, the balance she used before is now broken. The teacher tells Kia that she can tell how much water is left by looking. The water now comes up to t

It would need to be refilled up to the 100mL mark. I can't see the question itself so not sure exactly what it is asking.

$$density = \frac{mass}{volume}$$since  the beaker has volume marked on the side and the density of water is 1 g/cc so 1cc or 1ml of water would weigh 1gm. Just find the volume lost and the same number of grams is the mass of the water to be added.
