Measure the density of eggs with a densimeter, beaker, water and salt

Add water to the beaker, put the egg in, slowly add salt, and stir to make the salt melt away. When the egg just floats, the density of salt water is the density of the egg. Use the densimeter to measure the density of salt water. In addition, the densimeter can only measure the density of liquid
