The mass of a chicken egg is 90 g. The protein is 50% of the total mass, and the yolk is 74%

The mass of a chicken egg is 90 g. The protein is 50% of the total mass, and the yolk is 74% of the protein mass. Find the mass of the shell in grams.

1. Determine what is the mass of protein in an egg weighing 90 grams, if the protein is 50% of the egg mass:

90: 100 * 50 = 45 grams.

2. Determine what is the mass of the yolk, if it is 74% of the mass of the protein:

45: 100 * 74 = 33.3 grams.

3. Determine what is the mass of the egg without shell:

45+ 33.3 = 78.3 grams.

4. Determine what is the mass of the shell:

90 – 78.3 = 11.7 grams.

Answer: The mass of the shell without eggs is 11.7 grams.
