Context: The passage below describes an experiment. Read the passage and then follow the instructions below.

Emma poured four ounces of water into each of six glasses. Emma dissolved one tablespoon of salt in each of three glasses, and did not add salt to the other three. Then, Emma placed an egg in one glass and observed if the egg floated. She removed the egg and dried it. She repeated the process with the other five glasses, recording each time if the egg floated. Emma repeated this test with two more eggs and counted the number of times the eggs floated in fresh water compared to salty water.
